I'm using the system("pathping xxx.xxx.xxx > c:\i.txt") function to leave the program running pathping tests and saving the result to a file to analyze later.
Basically I wanted to play this function inside an infinite loop to always be analyzing but could not find a way to instead of i.txt use the variable i .
#include <stdio.h>
main(){
int i=0;
while(i>=0){
system("pathping xxx.xxx.xxx.xxx > i.txt");
i++;
}
return 0;
}
You need to format the string to put the variable within it. You can even concatenate string , but it is gambiarra *.
I would not do an loop infinite, just a big one. It is not to have problems of performance or of memory, but there will be problems when passing of 2 billion and little and would have to treat this, there begins to complicate the algorithm, and if it is to complicate, nor is it to do any of this. >
If you need a larger number, use a long or long long instead of int , with your due limit .
#include <stdio.h>
#include <limits.h>
int main() {
int i = 0;
while (i < INT_MAX) {
char buffer[100] = "";
sprintf(buffer, "pathping xxx.xxx.xxx.xxx > %d.txt\n", i++);
system(buffer);
}
}
I made an ideology slightly modified because I am not allowed to run the system () '. And yes, it is dangerous. Also on the Coding Ground .
Maybe take some time ( sleep or timer ) between one step and another is a good idea.
Inner Loop you can put:
while(true){
system("pathping xxx.xxx.xxx.xxx > i.txt");
i++;
}
