For loop and while loop are control structures used in programming to iterate over a block of code multiple times.

• For loop is used when the number of iterations is known beforehand.

• While loop is used when the number of iterations is not known beforehand and is based on a condition.

• Example of for loop: for(int i=0; i<5; i++) { //code block }

• Example of while loop: int i = 0; while(i < 5) { //code block i++; }
