My program isen't deleting the arrys, alwais stop at the point whan reaches the freeing pint. My code:

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
int main(){
    int n,m;
    scanf("%d %d",&n,&m);
    int** t;
    t=(int**)malloc(n);
    for(int i=0;i<n;i++){
        t[i]=(int*)malloc(m);
    }
    for (int i=0; i<n; i++){
        for(int j=0; j<m; j++){
            t[i][j] = rand() % 10;
            printf("%d ",t[i][j]);
        }
        printf("\n");
    }
    getch();
    for(int i=1;i<n;i++){
        free (t[0]);
    }
    free (t);
    return 0;
}

You are trying to free the first element several times, instead free each only once.

for(int i=1;i<n;i++){
    free (t[i]);
