Q. If sum of two integer is 14 and if one of them is 8 then find other integer. Ans: Well, this is very simple. Simply, one integer is 8 and sum of two integers is 14. So, we need to subtract the number 8 from their sum of 14 to get the second number. So, the second number is: 14 - 8 = 6 C-Program of this task Code---> #include<stdio.h> int main () { int num1 = 8 , num2 , sum = 14 ; num2 = sum - num1 ; printf ( "The second number is: %d" , num2 ); return 0 ; }
In this C-program we will calculate the factorial of a number. The number will be taken from the user.
input:
The number(i.e : 5,6,9 etc.)output:
The factorial of the given number
CODE---->
#include<stdio.h>
int main()
{
int i,n,fact=1;
printf("Enter a number: ");
scanf("%d",&n);
if(n<0)
{
printf("\n%d is a negative number. Factorial of a negative number doesn't exist.",n);
}
if(n==0)
{
printf("\nThe factorial of 0 is = 0");
}
if(n>0)
{
for(i=1;i<=n;i++)
{
fact=fact*i;
}
printf("\nThe factorial of %d is = %d",n,fact);
}
return 0;
}
