For factorial program the condition is must and should fact=fact*i let\'s check i is 0 and fact is 1 that declared in program. Check the conditions then we get the exact factorial of any number

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()
