c++ ping program
i just finished a c++ course in my school and i want to write a program to use at home, also for my dad to use. my dsl has been going out recently and i check the connection by pinging yahoo.com usually. but the ping program times out after a little while of no responces. so what i want to do is this, write a c++ program where it will ask you what host you want to ping, and it will open the ping program. now if there is a responce, it will output the responce and then the program will end. if there is no responce in a given amount of time, like 5 seconds, it will kill the ping program and restart it and keep trying until a responce is recieved. i want to do this in c++ because i will want to compile this for windows so my dad can use it, the only access to any compiler is at school, and only c++. so my question is this, in c++ how can i call an outside program? i will specify in the program where to look for the program, (/bin/ping) and when i want to compile it for windows i will just change the location. ive done this in a shell script with bash, and thats what i use now for when the dsl goes out, but this is a personal project of mine to get this running and mainly so my dad can use it. this is not a homework question.
