# C program to find all prime numbers from array

Program in the C programming language to find all the prime numbers from the inputted array. Below is the C program -

/* C program to find all prime numbers from the inputted array */ #include<stdio.h> #include<conio.h> void main() { int ar[100],i,n,j,counter; printf("Enter the size of the array "); scanf("%d",&n); printf("\n Now enter the elements of the array"); for(i=0;i<n;i++) { scanf("%d",&ar[i]); } printf(" Array is -"); for(i=0;i<n;i++) { printf("\t %d",ar[i]); } printf("\n All the prime numbers in the array are -"); for(i=0;i<n;i++) { counter=0; for(j=2;j<ar[i];j++) { if(ar[i]%j==0) { counter=1; break; } } if(counter==0) { printf("\t %d",ar[i]); } } getch(); }

Output -

Enter the size of the array – 5

Now enter the elements of the array – 23 98 45 101 6

Array is – 23 98 45 101 6

All the prime numbers in the array are – 23 101
