bookChallenge: Setting Iterations with the While Loop in C

A while loop in C repeatedly executes a block of code as long as a given condition is true. Here's a simple example to help you:

main.c

main.c

copy

              
123456

            
int i = 0;

while (i < 3) {
    printf("Iteration %d\n", i);
    i++;
}
Uppgift

Swipe to start coding

Write a function in C called powerCounter that takes two integer parameters a and b. The function should calculate the value of a raised to the power of b (that is, a^b) using a while loop. For each multiplication performed in the loop, increment a counter variable. The function must return the final value of the counter variable, which should be equal to b (the exponent).

  • Use a while loop to repeat the multiplication process exactly b times.
  • Start with a result variable set to 1.
  • For each iteration, multiply the result by a and increment the counter.
  • After the loop, return the counter variable.
