Question 5

Time: 00:00:00
Question: Consider the following iterative implementation
to find the factorial of a number:

int main(){

int n =6, i;

int fact = 1;

for(i=1;i<=n;i++){

_________

printf("%d",fact);

return 0;




}

}

Which of the following lines should be inserted to complete the above code?

fact = fact + i

fact = fact + i

fact = fact * i

fact = fact * i

i = i * fact

i = i * fact

i = i + fact

i = i + fact

printf("%c %d", ch, i);

return 0;

}

In the program we use the int data type for i but in the scanf we entered as %c. For int type we must use %d. So there no input for scanf()
