Help me please ... Why i cant execute this program?

Question

#include <iostream>
using namespace std;

int main() {
int a,b;
cin>>a;
gotoxy(1,1);
textcolor(GREEN);
cputs(a);
return 0;
}

Answer 1

gotoxy() is not defined in iostream,
so, you have to define it first then it may work,

COORD coordinate = {0,0}; //initialization

void gotoxy(int x, int y){
//function definition
coordinate.X = x; coordinate.Y = y; SetConsoleCursorPostion(GetStdHandle(STD_OUTPUT_HANDLE),coordinate);
}

void gotoxy(int x,int y)
{
printf("%c[%d;%df",0x1B,y,x);
}

/* here I gave 2 definition, you can use any one of them */

Answer 2

textcolor also not defined,
these all functions are defined in conio.h,
which is inbuild only in turboc++ or Borland c++,

but in others you have to define all these functions because there is no conio.h there.

instead of textcolor () ,
use system (" color 'background''foreground' ");

example:- system("color A1");
