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.
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.
- AX is the primary accumulator; it is used in input/output and most arithmetic instructions. For example, in multiplication operation, one operand is stored in EAX or AX or AL register according to the size of the operand. BX is known as the base register, as it could be used in indexed addressing.
- Definition of: unconditional branch. unconditional branch. In programming, a GOTO, BRANCH or JUMP instruction that passes control to a different part of the program. Contrast with conditional branch.
- In computer programming, a loop is a sequence of instruction s that is continually repeated until a certain condition is reached. Typically, a certain process is done, such as getting an item of data and changing it, and then some condition is checked such as whether a counter has reached a prescribed number.
The 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.
- 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.
- Traveling clockwise, the Beltway is designated as the "Inner Loop"; traveling counter-clockwise, it is designated as the "Outer Loop".
- 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.
