Q4) Write a program in C to input 10 numbers in a one dimensional integer array and print only the prime numbers from it.
A prime number is a number which is divisible by 1 and itself. Example: 13, 17, 19, etc.
Program
#include <stdio.h>
#include <conio.h>
int main()
{
int a[10], i,j,c=0;
printf("Enter 10 numbers\n");
for(i=0; i<10; i++)
{
scanf("%d",&a[i]);
}
printf("\nPrime Numbers\n");
for(i=0; i<10; i++)
{
c=0;
for(j=1; j<=a[i]; j++)
{
if(a[i]%j==0)
{
c++;
}
}
if(c==2)
{
printf("%d ",a[i]);
}
}
return 0;
}Output
Enter 10 numbers 5 12 18 23 17 45 93 62 7 54 Prime Numbers 5 23 17 7
