My issue

what is runtime error here

My code

#include <stdio.h>

int main() {
	// your code goes here
 int firstMatrix[100][100], secondMatrix[100][100], result[100][100];
    int M, N, P;
    scanf("%d %d", &M, &N);
    for (int i = 0; i < M; i++) {
        for (int j = 0; j < N; j++) {
            scanf("%d", &firstMatrix[i][j]);
        }
    }
    scanf("%d %d", &N, &P);
    for (int i = 0; i < N; i++) {
        for (int j = 0; j < P; j++) {
            scanf("%d", &secondMatrix[i][j]);
        }
    }
    for (int i = 0; i < M; i++) {
        for (int j = 0; j < P; j++) {
            result[i][j] = 0;
            for (int k = 0; k < N; k++) {
                result[i][j] = result[i][j]+(firstMatrix[i][k] * secondMatrix[k][j]);
            }
        }
    }
          for (int i = 0; i < M; i++) {
        for (int j = 0; j < P; j++) {
            printf("%d ", result[i][j]);
        }
        printf("\n");
    }

    return 0;
}
