***My Code in C***

#include<stdio.h>

int main() {

    int i = 0;
    int j = 0;
    int h;
    char x = '+';
    char y = '%';
    int matrix[7][7];
    
    for (i = 0; i < 7; i++) {
        printf("\n");
        
       
        
        for (j = 0; j < 7; j++) {
            printf("\t%c", x);
        }

       
        }

        return 0;
    }

***End***

I need to replace the symbols under the blue line.

Thank you.
