Dear All,
How to execute other program within a C program?
For example,
I have a one program. This program executes in command prompt as follows. The aguments of SNMP.exe program is "526" and "localhost".
C:\>SNMP.exe 526 localhost
I want to execute the "SNMP.exe" program within a C program using system() function or others.
Please give me simple example.
Thank you in advance.

Thank you in advance.
Here is the example for using system(),
But it is not the efficient way in C .For efficiency use execlp.Code:#include<stdio.h>
main()
{
system("test.exe 5434 localhost");
}

If C program have a prameter, How to use the system function?
main (int argc, char **argv) {
system ("test.exe %s %s", argv[1], argv[2])
}
Is it right?
If by this you mean how do you call another program whose command line arguments are given as the command line arguments to your program, then yes.Quote:
