How to create map with random numbers inside in c - c

Question

I have task about printing board where you should input dimension and program will create a board with 2 numbers inside each cell: 1'st number is random from 1-3 and second one should be zero. I can make it only with zero but when i tried to make a random number everything went wrong way..
Maybe anyone knowns what it wrong with it?
Function calls uploading map:
int randfunc(int i, int n);
int uploadmap(int m,int n){
int a[m][n];
int i,j,k;
// time_t t;
//srand((unsigned)time(&t));
//int randnum = rand() % 3 + 1;
for(i = 0; i < m;i++){
printf("+---");
}
printf("+\n");
memset(a,0,sizeof(a));
for(i = 0;i < m;i++){
for(j = 0; j < n;j++){
printf("|%d %d",randfunc(i,n),a[i][j]);
}
printf("|\n");
for(k = 0;k < m;k++){
printf("+---");
}
printf("+\n");
}
return 0;
}
function which calls random numbers from 1 to 3:
int randfunc(int i, int n) {
time_t t;
srand((unsigned) time(&t));
for( i = 0 ; i < n ; i++ ) {
printf("%d\n", rand() % 3 + 1);
}
return 0;
}
Main function :
int main(int argc, const char * argv[]) {
int m,n;
printf("Enter dimension: \n");
scanf("%d %d",&m, &n);
printf("Map has been uploaded %d\n",uploadmap(m,n));
return 0;
}

The following simple code could work:
#include <stdio.h>
#include <stdlib.h>
void uploadmap(int m,int n) {
for (int i = 0;i < m; ++i) {
for(int j = 0; j < n; ++j)
printf("|%d 0", (rand() % 3)+1);
printf("|\n");
}
}
int main() {
int m, n;
printf("Enter dimension: \n");
scanf("%d %d",&m, &n);
uploadmap(m,n);
return 0;
}
