How to buid and run a program


Good evening/ morning to the gentlemen and ladies in the forum. I am quite new to this and I hope my post adheres to the group rules.
I am relatively a newbie to using code::blocks to write programs and execute them. I did C programming in university (graduated in 2008) but to a very basic level. I have recently decided to pick up programming , now in C++ cause I intend to grow my skill and build applications. To this end I will be writing a program or two a day for the next 90 days to see how far I will go from there.

My first program of today is as follows:

#include <iostream.h>
#include <conio.h>

int main()
    int value1, value2, sum;
    cout<<"Enter first value:";
    cout<<"Enter the second value:"
    sum = value1 + value2;
    cout <<"\n";
    cout << "The sum of the given values is: ";
    cout << sum;
    return 0;

just a simple program to add two numbers so really it shouldnt be a problem. However, something is amiss with my code::blocks because I am not being able to compile or run it and I suspect that I need some help setting up the code::blocks compiler. I am getting the following error message

Build file: " no target" in "no poject" (compiler: unknown)
fatal error: iostream.h: No such file or directory
Build failed: 1 error(s), ) warnings(s)

May someone advise me how to configure the compiler and also how to import a singular file into a project. Thank you


Get City College of NY:

Read the section on First project.



Where did you install the Compiler?
What operating system?
What error did you get? Post the build log information.
