Did you try backwhacking the path to the file? ie - using double backslashes instead of single?

C:\Windows\ -> C:\\Windows\\

yeah ..
i tried it but its still giving the error ..i.e. output -1

my exe file was developed through turbo c++ itself

Can I see the system() call you're using?

[abhisheknaina]

my program was


main() {
int i;
i = system("c:\\turboc3\\sim.exe");

cout<< i;
}

U can use any of the following two method:

#include<stdio.h>
#include<process.h>
 
int main()
{
    int c = execl("C:\\TC\\BIN\\SU.EXE", NULL);
 
    printf("%d",c);
    return 0;
}
 

#include<stdio.h>
#include<process.h>
 
int main()
{
    int c = spawnl(P_OVERLAY, "C:\\TC\\BIN\\MM.EXE", NULL);
 
    printf("%d",c);
 
    return 0;
}
