So I am a student from UAT and just wanted to throw in my 2 cents. I put in my ideas but I was still having a problem with the code adding another blank space when the user number is posted. See what you think!

Code:
#include<stdio.h>  // interger to pointer without cast PROBLEM....
#include<stdlib.h> // SOLUTION :  whenever using string the data type  
// of the array must be char

void welcome();
void rand_mines(char msweep[12][12]);
void printmatrix(char msweep[12][12],int r,char user_chart[12][12]);
int process(char msweep[12][12],int r,int c,char user_chart[12][12]);

int main()

{
    welcome();
    char msweep[12][12] = {{'0'}};      
    int i,r,c;   
    char user_chart[12][12] = {{'0'}};
    rand_mines(msweep);  
    printf("Where is your first guess?\n");
    printf("Enter your location between 1 - 11.\n");
    printf("Enter x variable\n");
    scanf("%d",&r);
    printf("Enter y variable\n");
    scanf("%d",&c);
    printmatrix(msweep,12,user_chart);  
    i = process(msweep,r,c,user_chart);
    while(i == 1)     
    {
    printf("Lucky BRAT, live on for another step\n");      
    printf(" %c Surrounding MINEs\n\n",msweep[r][c]);
    printmatrix(msweep,12,user_chart);
        printf("Enter your location between 1 - 11.\n");
        printf("Enter x variable\n");
        scanf("%d",&r);
        printf("Enter y variable\n");
        scanf("%d",&c);
    i=0; 
    i = process(msweep,r,c,user_chart);    
    }  
    if(i==0)
    printf("Game OVER, ta ta. you stepped on a MINE !!\n");
    return 0;
