Alternatives of goto in my C++ console application -

i've got point had deal logic in c++ project, , unfortunately not able right using goto.

what problem ?

i have 1 function, named processrunning(const char *name) verifies if process exists (it returns true) or not (it returns false).

i have 4 functions, int fun1(const char name[]),int fun2(const char name[]),int fun3(const char name[]), int fun4(const char name[]). - each of these functions looks this:

int fun1(const char name[]){     //open new .bat file      //start of write in .bat      //taskkill  process.exe     //start again process.exe     //delete created file      //end of write in file     return system(name); } 

and same other 3 functions.

now, in main() program trying following:

int main(){     //...     start_again:     if(processrunning("process1.exe")){         fun1("fun1.bat");         goto start_again;     }     else if(processrunning("process2.exe")){         fun1("fun2.bat");         goto start_again;     }     else if(processrunning("process3.exe")){         fun1("fun3.bat");         goto start_again;     }     else if(processrunning("process4.exe")){         fun1("fun4.bat");         goto start_again;     }     else if(!processrunning("process1.exe") || !processrunning("process2.exe") || !processrunning("process3.exe") || !processrunning("process4.exe") || ){         goto start_again;     }     goto start_again;     return 0; } 

now whole program do:

• the program must run;
• it checks if 1 of 4 processes running;
• if there's no such process, go , check again (so there's permanent check if of conditions aren't satisfied)
• if finds process1 (the first if), creates .bat file , executes (kill first process, start again, delete .bat file). process running, program should still go through other ifs , check if there's process2, process3 or process4 running , same thing them.

every process assigned application, let's say:

app1 -> goes process1
app2 -> goes process2
..
app4 -> goes process4

cases:

• process1 running
• process1 not running
  ..
• and on
  sake of example i'll take process1 should apply of them.

because app running, checks if there's process1. if there isn't, checks process2 , if none found, start on again , again. otherwise, if process1 found, what's in if condition still after other processes.

now, problem have can't find better solution keep console program running time , make these checks. more, actual implementation i've found far doesn't treat situations.

any advices on this, please (improvements of logic, critiques, alternatives)? (sorry long post , possible grammar mistakes).

if want check existance of each process every loop , want run forever can use while loop.

int main(){     //...     while(true) {         if(processrunning("process1.exe")){             fun1("fun1.bat");         }         if(processrunning("process2.exe")){             fun1("fun2.bat");         }         if(processrunning("process3.exe")){             fun1("fun3.bat");         }         if(processrunning("process4.exe")){             fun1("fun4.bat");         }     }     return 0; } 

we don't want use else if here never check process if 1 process found. using if check each process each iteration.

edit:

from comments appears want run function once. can add bool each process , check in if condition. if true not run function again. can change code to:

int main(){     //...     bool proc1 = false, proc2 = false, proc3 = false, proc4 = false,     while(true) {         if(!proc1 && processrunning("process1.exe")){             fun1("fun1.bat");             proc1  = true;         }         if(!proc2 && processrunning("process2.exe")){             fun1("fun2.bat");             proc2  = true;         }         if(!proc3 && processrunning("process3.exe")){             fun1("fun3.bat");             proc3  = true;         }         if(!proc4 && processrunning("process4.exe")){             fun1("fun4.bat");             proc4  = true;         }     }     return 0; } 

now if procx false check if process running , if run fun1() set procx true. otherwise if procx true rest of if statement skipped.
