[Dev-C++] execution of a string with system()

[Simon J. <el...@op...>]

Hello everybody,

I tried to write a programm which does execute some dos command (like tracert, ping etc.) with an ip.

At first, I created a string (#include <string>), but when I tried to execute it with the system()-command, I got the following error (exec=string-Variable):
"cannot convert 'exec' from type string to type 'const char*'"

Finally -after some hours of trying :)- I've got the following solution:

#include <iostream> 
#include <stdlib.h>


int main()
{ 
int i;
char pcno[20];

cout << "Enter the ip to trace:" , cin >> pcno; //enter domain-name of pc (domain-name is supposed to be 8 chars long)

for (i=0;i<8;i++){pcno[i+8]=pcno[i];}; //put the domain name at the end
pcno[0]='t';
pcno[1]='r';
pcno[2]='a';
pcno[3]='c';                           //enter the dos-command in the first chars
pcno[4]='e';
pcno[5]='r';
pcno[6]='t';
pcno[7]=' ';
for (i=16;i<40;i++){pcno[i]=' ';};

system(pcno);
system("PAUSE");
return 0; 
} 


Does someone know an easier solution?

Tanks for your help.

Simon
