C Program to find the Largest Prime number less than the given number.

Given a number (as command line argument), find the Largest Prime number less than the given number. For e.g., given 8, the program should return 7.

#include <stdio.h>

int main()

{

    int i,n=2,m,j=0;

    int a[100]={'\0'};

    printf("enter the number in the range[3-500]\n");

    scanf("%d",&m);

    while(n<m)

    {

        for(i=2;i<n;i++)

        {

            if(n%i==0)

            goto t;

        }

        a[j++]=n;

        t : n++;

    }

    printf("largest prime number less than given number is %d\n",a[--j]);

}
