Using For Loop
Below is the C program to check prime numbers using for loop:

// C program to demonstrate whether
// a number is prime or not using
// for loop
#include

// Defining the function
int primenumber(int number)
{
int i;

// Condition for checking the
// given number is prime or
// not
for (i = 2; i <= number / 2; i++)
{
if (number % i != 0)
continue;
else
return 1;
}
return 0;
}

// Driver code
int main()
{
int num = 7, res = 0;

// Calling the function
res = primenumber(num);
if (res == 0)
printf("%d is a prime number", num);
else
printf("%d is not a prime number", num);
}
Output
7 is a prime number
