Thread: WinAPI > C -- Executing a program

Good evening, So i've this project to create a window where i can execute programs from. I'm really tired of searching so i decided to ask for someone's help. anyways i made a program that shows a window etc but my problem is that i want to execute some functions, such as printf("hello world!").. I dont' know how to bring that .exe file and i don't know how to put it, i've a feeling that i've to use createProcess but i don't know how to put it. To be more specific: i wanna execute this simple program on my window:
int n;printf("Enter an integer");scanf("%d",n);
for example, that's what i want. Hope that you get what i mean. Program used: Code::Blocks Language: C, not c++. Thanks.

Yes i know GReaper but i don't know how to use it can you give me an example? with creating a process and a simple program like a : printf() and scanf()?
Would be really appreciated.

something like the last thing you said: Like pressing a button that runs a specified function.
Okay i've attached a picture :
You see in files>TP N°1>Exercice 1:
when i click on exercice one i want to get an executed program like in stdio. just a .exe file where there's printf("enter n");scanf("%d",&n)
Hope that you get what i meant, thanks.

@GReaper, yeah i've read that but i didn't understand how to put it on my program.
