Question

Study the following code with a while-loop and convert it to a for-loop (fill in the blanks).

int i=4, result=1; while(i>1) { result *= i; i--; }

The following for-loop performs the same functionality:

int result=1; for (__________ i=4; i _________1;____________) { result *= i; }

Answer 1

Given Code with while-loop

int i=4, result=1;

while(i>1)

{

result *= i;

i--;

}

It is clear from the value of i that the while loop terminates after i-1 numer of iterations, and performs the product of all the values of i

The for loop representation of the same will be like

int result=1;

for(int i=4;i>1;i--)

{

result*=i;

}
