Beh il discorso e semplice non mi funzione si incasina proprio dove c'e il prodotto e non capisco dove sia l'errore vi prego
grazie a tutti

Codice PHP:

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

#define N 100

main(){
     int m[N][N],m1[N][N],mp[N][N],i,j,r1,c1,r2,c2,k;
     
     do{
     printf("Inserire numero righe della matrice1  ");
     scanf("%d",&r1);
     if((r1<1)||(r1>100))
       printf("Errore");
     }while((r1<1)||(r1>100));
     
     do{
     printf("Inserire numero colonne della matrice1  ");
     scanf("%d",&c1);
     if((c1<1)||(c1>100))
       printf("Errore");
     }while((c1<1)||(c1>100));
     
     do{
