Im new to C and i really need your help

All of that works okey (for me), except printf("%c ",output_name[0][i]);

My idea is print the name first then “-” and “_” but my code only work with one-character name, i tried several ways but still not work.

Here is my code

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

int main()
{
    int n;
    scanf("%d", &n);
    int m;
    scanf("%d", &m);
    char input_name[n][9];
    char input_signal[n][26];

    char output_name[m][1];
    char type[m][5];
    char input_name_1[m][1];
    char input_name_2[m][1]; 
    int input_value_store_1;
    int input_value_store_2;
    for (int i = 0; i < n; i++) {
        scanf("%s%s", input_name[i], input_signal[i]);
    }

    for (int i = 0; i < m; i++) {  
        scanf("%s%s%s%s", output_name[i], type[i], input_name_1[i], input_name_2[i]);
    }
    
    for (int i=0; i < m; i++) {
        printf("%c ",output_name[0][i]); 
        for (int j=0; j<sizeof(input_signal[i]); j++)
            {
                if (input_signal[0][j] == '-' ) input_value_store_1 = 1; 
                else input_value_store_1 = 0;

                if (input_signal[1][j] == '-' ) input_value_store_2 = 1; 
                else input_value_store_2 = 0;
                

                if (strcmp(type[i], "AND") == 0) {
                    if ((input_value_store_1 == 1) && (input_value_store_2 == 1))
                        printf("-");
                    else printf("_"); 
                } 

                else if (strcmp(type[i], "OR") == 0) {
                    if ((input_value_store_1 == 1) || (input_value_store_2 == 1))
                        printf("-");
                    else printf("_"); 
                }

                else if (strcmp(type[i], "XOR") == 0) {
                    if (((input_value_store_1 == 1) || (input_value_store_2 == 1)) && (input_value_store_1 != input_value_store_2))
                        printf("-");
                    else printf("_"); 
                }

                else if (strcmp(type[i], "NAND") == 0) {
                    if (!((input_value_store_1 == 1) && (input_value_store_2 == 1)))
                        printf("-");
                    else printf("_"); 
                }

                else if (strcmp(type[i], "NOR") == 0) {
                    if (!((input_value_store_1 == 1) || (input_value_store_2 == 1)))
                        printf("-");
                    else printf("_"); 
                }

                else if (strcmp(type[i], "NXOR") == 0) {
                    if (!(((input_value_store_1 == 1) || (input_value_store_2 == 1)) && (input_value_store_1 != input_value_store_2)))
                        printf("-");
                    else printf("_"); 
                }
            }
        printf("n");
    }
    return 0;
