scanf 2d array size C -


i've tried make custom array size by:

#include <stdio.h> #include <stdlib.h>  int main() {     int x;     int y;      printf("array size:");     scanf("%d %d", &x, &y);      int kancelar[x][y];     int i;     int q;      (q = 0; q < x; q++)         (i = 0; < y; i++)             kancelar[q][i] = getchar();      (q = 0; q < x; q++)         (i = 0; < y; i++)             putchar(kancelar[q][i]);      return 0; }

but no luck, values wrong. i'm using c,

you getting messed newlines present in input buffer press of enter key after each input. need consume newline each time before going getchar().

a simple solution may like

printf("array size:"); scanf("%d %d%*c",&x,&y);  //eat newline int kancelar[x][y]; int i; int q; for(q = 0;q < x;q++) {     for(i = 0;i < y;i++ )     {         kancelar[q][i] = getchar();         getchar(); //eat newline     }  }
