Question
QUESTION: Case:- Im my desktop, there is an ITQUE.EXE file.
Que:-  I want to make a program in C language to Run this ITQUE.EXE file. Plz give me the program.

ANSWER: Hi Dear ashok !

A group of built- in functions are available to perform this task suppose you are working in c:\tc directory  , and you wish to execute a EXE file named "sample.exe"
just use the "spawnl()" function available in process.h header  file

FILE : sample.c
void main()
{
 printf("Sample .c Program\n");
}
/* save and compile the file */


FILE: EG.C
void main()
{
 spawnl(P_WAIT  , "sample.exe" , NULL);
 printf("This is from eg");
}

The output of eg.c will be:
sample.c Program
This is from eg

this simple C program will execute your sample.exe program and return control to the main program .


Here what you supposed to do is to specify the correct path name (  where your .EXE file located in your system . ) as a second argument to the spawnl() function .

Please revert me in case of issues !

With Thanks and Regards !

QUESTION: Not working....

Program were running but not giving output of sample.exe.

My query is still to be Resolved

Answer
Hi dear Ashok !

I didn't find any problem withis programme , here is an alternate solution of you ! If you are using Turbo C/C++ compiler then you can insert the function getch(); at the end to view the result in the same output window !

Note : Before executing the second programme "eg.c" make sure that you should already have an exe of sample.c ( say sample.exe ) if not load the programme sample.c onto the editor and compile and execute once it will create sample.exe !

Thanks and Regards !
