Hi, so I just want to know how to input a command line in repl. I'm aware that in C you simply type the program name followed by the arguments you want to give main. So how do I open the command line to begin with and what input should i give to run it.

This is the program I want to run:

#include <stdio.h>

// Taking argument as command line
int main(int argc, char *argv[])
{
int a, b, c;

// Checking if number of argument is 
// equal to 4 or not. 
if (argc < 4 || argc > 5)  
{ 
    printf("enter 4 arguments only eg.\"filename arg1 arg2 arg3!!\""); 
    return 0; 
} 

// Converting string type to integer type 
// using function "atoi( argument)"  
a = atoi(argv[1]);  
b = atoi(argv[2]); 
c = atoi(argv[3]); 

// Checking if all the numbers are positive of not 
if (a < 0 || b < 0 || c < 0)  
{ 
    printf("enter only positive values in arguments !!"); 
    return 1; 
} 

// Checking if all the numbers are different or not 
if (!(a != b && b != c && a != c))  
{ 
    printf("please enter three different value "); 
    return 1; 
} 
else
{ 
    // Checking condition for "a" to be largest 
    if (a > b && a > c)              
        printf("%d is largest", a); 

    // Checking condition for "b" to be largest     
    else if (b > c && b > a)  
        printf ("%d is largest", b); 

    // Checking condition for "c" to be largest.. 
    else if (c > a && c > b)  
        printf("%d is largest ",c); 
} 
return 0; 

}
