function - How to properly use system() to execute a command in C++?

I am new to C++ programming under Windows. I am trying to execute a command say cuobjdump in C++ code using the system() function:

system("C:\program files\nvidia gpu computing...\cuobjdump.exe --dump-cubin C:\..\input.exe");

output:

Usage  : cuobjdump [options] <file>

This followed by the list of the options for cuobjdump.

When I execute this program I always get the cuobjdump help options displayed in the command line. It's as if the system call does not parse the filename. What am I doing wrong? I get the same result while using createprocess. The options --dump-cubin gives an error as if I mistyped it.

Give a try with (that is, surrounding cuobjdump.exe path with ", properly escaped in C++ as "):

system(""C:\program files\nvidia gpu computing...\cuobjdump.exe" --dump-cubin C:\..\input.exe");
