Here is a simple code using command line argument to print multiple number of strings with "_" between them.

To check the output , type this in command prompt : filename ABC 5
OUTPUT: ABC_ABC_ABC_ABC_ABC

Code
 


#include<stdio.h>


#include<stdlib.h>


 


int main(int argc, char *argv[])


{


        if(argc<2)


        {


                printf("Enter CLA") ;


                return 0 ;


        }


        


    printf("%s",argv[1]) ;


         


        int n = atoi(argv[2]) ; 


 


    for(int i=0;i<n;i++)


        printf("_%s ",argv[1]) ;


        return 0 ;


        


}
