AnswersDriveThe jnz (or jne) instruction is a conditional jump that follows a test. It jumps to the specified location if the Zero Flag (ZF) is cleared (0). jnz is commonly used to explicitly test for something not being equal to zero whereas jne is commonly found after a cmp instruction.
Moreover, what is JLE in assembly?
The jle instruction is a conditional jump that follows a test. It performs a signed comparison jump after a cmp if the destination operand is less than or equal to the source operand.
What do you mean by conditional and unconditional jump?
Conditional Jump Instructions are an important aspect of the decision making process in programming. Whereas Unconditional jump instruction is a branch instruction same as conditional jump instruction and Unconditional Jump Instruction enables the programmer to set up continuous loop.

What is a for loop used for?
In computer science, a for-loop (or simply for loop) is a control flow statement for specifying iteration, which allows code to be executed repeatedly. For-loops are typically used when the number of iterations is known before entering the loop.
2
How do while loops work?
In most computer programming languages, a while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement.
3
What is the use of do while loop in C?
Advertisements. Unlike for and while loops, which test the loop condition at the top of the loop, the dowhile loop in C programming checks its condition at the bottom of the loop. A dowhile loop is similar to a while loop, except the fact that it is guaranteed to execute at least one time.
4
What is a nested for loop?
A nested loop is a loop within a loop, an inner loop within the body of an outer one. Then the second pass of the outer loop triggers the inner loop again. This repeats until the outer loop finishes. Of course, a break within either the inner or outer loop would interrupt this process.
5
What is a nested loop in C++?
Nested loops in C++ Programming. A loop inside another loop is called a nested loop. The number of loops depend on the complexity of a problem. Suppose, a loop, outer loop, running n number of times consists of another loop inside it, inner loop, running m number of times.
6
What is an inner loop?
In computer programs, an important form of control flow is the loop which causes a block of code to be executed more than once. A common idiom is to have a loop nested inside another loop, with the contained loop being commonly referred to as the inner loop.
7
What is the inner loop of the Beltway?
Traveling clockwise, the Beltway is designated as the "Inner Loop"; traveling counter-clockwise, it is designated as the "Outer Loop".
8
What is nested for loop in C?
A loop inside another loop is called a nested loop. We can have any number of nested loops as required. Consider a nested loop where the outer loop runs n times and consists of another loop inside it. The inner loop runs m times. Then, the total number of times the inner loop runs during the program execution is n*m.
9
What is the use of break in C?
The break statement in C programming has the following two usages − When a break statement is encountered inside a loop, the loop is immediately terminated and the program control resumes at the next statement following the loop. It can be used to terminate a case in the switch statement (covered in the next chapter).
10
What is the use of strcmp function in C?
C Language: strcmp function. (String Compare) In the C Programming Language, the strcmp function returns a negative, zero, or positive integer depending on whether the object pointed to by s1 is less than, equal to, or greater than the object pointed to by s2.
11
What is the Strcpy?
C Language: strcpy function. (String Copy) In the C Programming Language, the strcpy function copies the string pointed to by s2 into the object pointed to by s1. It returns a pointer to the destination.
12
What is Strcat?
char *strcat(char *dest, const char *src) It takes two arguments, i.e, two strings or character arrays, and stores the resultant concatenated string in the first string specified in the argument. The pointer to the resultant string is passed as a return value.
13
What does ITOA do in C?
The itoa (integer to ASCII) function is a widespread non-standard extension to the standard C programming language. itoa takes the integer input value input and converts it to a number in base radix . The resulting number (a sequence of base- radix digits) is written to the output buffer buffer .
14
What is Strncpy?
C Language: strncpy function. (Bounded String Copy) In the C Programming Language, the strncpy function copies the first n characters of the array pointed to by s2 into the array pointed to by s1. It returns a pointer to the destination.
15
What is a substring in C?
C substring, substring in C. A substring is itself a string that is part of a longer string. For example, substrings of string "the" are "" (empty string), "t", "th", "the", "h", "he" and "e". Header file "string.h" does not contain any library function to find a substring directly.
16
What does Snprintf do in C?
snprintf is essentially a function that redirects the output of printf to a buffer. This is particularly useful for avoiding repetition of a formatted string. You can build a string once and use printf("%s", mystr) instead of print("%d,%s,%f,%d", x,y,z,a) every time, which gets cumbersome with actual variable names.
17
What is a buffer in C programming?
The idea of buffering is general in computation, it is not specific to C. A buffer is an area of memory, set aside for temporary storage of data. a data buffer (or just buffer) is a region of a physical memory storage used to temporarily store data while it is being moved from one place to another.
18
What is Fflush in C?
Use of fflush(stdin) in C. fflush() is typically used for output stream only. Its purpose is to clear (or flush) the output buffer and move the buffered data to console (in case of stdout) or disk (in case of file output stream).
19
What is a buffer overrun?
In information security and programming, a buffer overflow, or buffer overrun, is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory locations. On many systems, the memory layout of a program, or the system as a whole, is well defined.
