whats wrong here??

using vc++, trying to calculate area of triangle..

Code:

---

#include <iostream.h>
#include <conio.h>
int a,x,y,z;

int calcu(x,y)
{
        z="0.5"*x*y;
        return z;
}
int main()
{
        cout<<"Enter base: ";
        cin>>x;
        cout<<"Enter height: ";
        cin>>y;
        calcu(x,y);
        cout<<"Area="<<z;
        cout<<"\nAgain? (y/n)";
        cin>>a;
        if a="y"
        {
                clrscr();
                main();
        }
       
        return 0;
}

---

get errors:

Code:

---

D:\Programming\c\triangle calc\Cpp1.cpp(6) : error C2448: '<Unknown>' : function-style initializer appears to be a function definition
D:\Programming\c\triangle calc\Cpp1.cpp(16) : error C2065: 'calcu' : undeclared identifier

10x thanks

I think you need to go read your book again

Code:

---

#include <iostream.h>
#include <conio.h>
int a,x,y,z;

int calcu(x,y)
{
        z="0.5"/*<------ is a string. You're multiplying a string with a number.*/  *x*y;
        return z;
}
int main()
{
        cout<<"Enter base: ";
        cin>>x;
        cout<<"Enter height: ";
        cin>>y;
        calcu(x,y);
        cout<<"Area="<<z;
        cout<<"\nAgain? (y/n)";
        cin>>a;
        if a="y" Also a is an integer and you're trying to store a character in it. :confused: And calling main()????:confused:
        {
                clrscr();
                main();
        }
       
        return 0;
}

Honestly. Do what salem said.

10x thanks

---

you have many errors man first of all function calcu u have to say

Code:

---

int calcu(int x,inty)

---

also a is character to integer !!!!!!

anyway i wrote a code for u ... i didnt run it so try to run it and see

Code:

---


 #include<iostream>
using namespace std;
int main()
{
  int x,y,z;
  char a;
    do

  {

 cout<<"enter base :\n";
cin>>x;
cout<<"enter height:\n";
cin>>y;
z=0.5*x*y;
cout<<"area of the triangle "<<z<<endl;
cout<<"enter y to continue \n";
cin>>a;
}

while((a=='y')||(a=='Y'));
return 0;
}

---

i think it will work :)

thanks M_Ghani for your ideas..
my final working code:

Code:

---

#include <iostream.h>
int x,y;
char a;

int calcu(int x,int y)
{
        return 0.5*x*y;
}
int main()
{
        do
        {
        cout<<"Enter base: ";
        cin>>x;
        cout<<"Enter height: ";
        cin>>y;
        cout<<"Area="<<calcu(x,y);
        cout<<"\nAgain? (y/n)";
        cin>>a;
        }

        while ((a=='y')||(a=='Y'));
        return 0;
}
