how to use linux commands in a cprogram?

hi .

Can anyone tell me how to use the linux commands while writing a c program. eg we are writing a program and we need to find out the total cpu usage during its execution so how we'll be implementing it.

Could you be a little clearer in what you need? What do you mean with "linux commands"? If you want to run some command from a console (or that runs in one), use:
system("command");
where command is the code to be run in the console.

you can also use the exec functions family. more sophisticated but a bit more complicated. check them out with your C programming reference

i need to make a c program in simple terms and need to find the total memory usage during execution.After that i have to print the o/p to on the Jsp Or Php or any presentsble language page.
thus in that form I was wondering as how to use the linux commands.
