Run a C++ Project main() multiple times in Visual Studio? -

i have visual studio c++ project. if want run once, can manually input arguments of

int main(int argc, char** argv) 

into debugging options , click debug.

however now, wish run multiple times different parameters in 1 go. e.g. wish run this:

for(i=0; i<10; i++) {     main(i); } 

how may visual studio?

i don't believe it's technically legal (per standard) call main. if were, you'd passing wrong parameters (argc == 1 , argv == ${deity}_only_knows).

this problem perhaps solve cmd script. make sure program compiled, run like:

@echo off cd \path\to\debug\dir rem bit can complex cmd.exe allows: /l %%a in (0,1,50) (     /l %%b in (0,1,10) (         echo data.txt result.txt %%a %%b     ) ) 

this run command (echo in case can see working should replace actual executable name, , modify cd command select proper directory) 561 times (51 x 11) first 2 arguments fixed , last 2 running 0-50 , 0-10, output of finishes:

: : : : : : : : : : data.txt result.txt 49 7 data.txt result.txt 49 8 data.txt result.txt 49 9 data.txt result.txt 49 10 data.txt result.txt 50 0 data.txt result.txt 50 1 data.txt result.txt 50 2 data.txt result.txt 50 3 data.txt result.txt 50 4 data.txt result.txt 50 5 data.txt result.txt 50 6 data.txt result.txt 50 7 data.txt result.txt 50 8 data.txt result.txt 50 9 data.txt result.txt 50 10 

there may way vs automatically part of build/run sequence i'm not aware of (and tend opt simplest solutions of time).

you could, of course, refactor code rename main else have filter main follows:

int main (int argc, char *argv[]) {     // normally:     return worker (argc, argv);      // or debugging:     // int stat = 0;     // (int = 0; < 10; i++) {     //     // construct argv-lookalike based on i.     //     stat = worker (myargc, myargv);     //     if (stat != 0) break;     // }     // return stat; 

however, construction of argv-array not trivial since have follow same rules laid out in standard, argc , argv must agree, argv must array of character pointers (one more indicated argc) each argument c-style string, argv[0] must represent program name, argv[argc] must null, , on.

it's easiest use cmd script solution , let startup code take care of argument preparation you.
