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 check a number is Prime or not. The number will be taken from the user.
input:
The number(i.e : 5,6,9 etc.)output:
The number will be Prime or not
CODE---->
#include<stdio.h>
int main()
{
int i,n,f=0;
printf("Please,Enter a positive number: ");
scanf("%d",&n);
if(n==0||n==1)
{
if(n==0)
printf("You entered ZERO.\n0 is not a Prime number or not a Composite number.\n");
else
printf("You entered ONE.\n1 is not a Prime number or not a Composite number.\n");
}
else
{
for(i=1;i<=n;i++)
{
if(n%i==0)
f=f+1;
}
if(f==2)
printf("%d is a Prime number.\n",n);
else
printf("%d is not a Prime number.\n",n);
}
return 0;
}

RESULT :
Please,Enter a positive number: 89 89 is a Prime number. -------------------------------- Process exited after 1.869 seconds with return value 0 Press any key to continue . . .
