array bound is not an integer constant before

[Jabbar Ali Soomro]

Please Help me When ever
Getting error “array bound is not an integer constant before ']' token”
‪#‎include‬ <iostream>
using namespace std;
int maxr;
int maxc;
void readmatrix(int m[maxr][maxc]); // size depend upon input of maxr and
// maxc
main()
{
cout<<"enter Number of Row :";
cin>>maxr;
cout<<"enter Number of columb :";
cin>>maxc;
}

Move these

int maxr;
int maxc;

Inside main. Dont use globals.

Looking at your function, you want to send in a 2D array?

you declare an array with index specified with non constant variable.
when you declare 2d array , the 2nd index must be specified only with a number or a constant variable.

Wait , is your array dynamic or static ... most likely i'll guess it's static and if that's the case you're not allowed to do this

cout<<"enter Number of Row :";
cin>>maxr;
cout<<"enter Number of columb :";
cin>>maxc;

That only works for dynamic arrays, static arrays dimensions must be const values, so your variables in main should be like

const int maxr=/*some value*/; 
const int maxc=/*some value*/;

also, it is a good habit to call global var with scope operator

std::cin >> ::maxr;
