Question

I need to modify below code to have output like: Example: RBGY

[ You have 1 white flag and you have 1 red flag]

Example: CCGG

[ You have 0 white flag and you have 1 red flag]

==================================

#include <stdio.h>
#include <string.h> 
#include <time.h>
#include <stdlib.h>

#define SIZE_STRING 4
#define SIZE_STRING_LONG 15


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

    if(argc != 2) {

        printf("Usage: ./main <scComputer>");
        exit(0);
    }

    char szUser[SIZE_STRING_LONG];
    char *szComputer = argv[1];
    int counter=0;
    int colour=0;
    int position=0; 
    char alreadyChecked[SIZE_STRING];


    printf("

 You have 8 changes to get it right. 
");           

    printf("

 Computer choses %s", szComputer); //check if the program works allright

    do{
        counter++;
        position=0;
        colour=0;
        memset(alreadyChecked, 0, sizeof(alreadyChecked));
        printf("
 ===================================================
");
        printf("
 Chance %d", counter);
        printf("

 Please enter your 4 colours choice");
        printf("
 (Please write capital letters without space  ");
