Convert string to int
Hi all,
How would I go about converting a string to an integer?
I have this string: "[MAN],0,50,50;"
The values can range between 0 and 100, I split the string up using the commas so that string a = 0, b = 50, c = 50.
How would i convert a,b, and c into integers?
Thanks, Nick

Once you have the string split up you can use atoi to convert them to ints.
This code destroys the original char array and strtok isn't thread-safe, but it sounds like perhaps you have a way of parsing your string already.
#include "mbed.h"
Serial pc(USBTX,USBRX);
int main()
{
char input[] = "[MAN],0,50,50;";
char *token;
int a,b,c;
pc.baud(9600);
pc.printf("input = %s\r\n", input);
token = strtok(input, ",;");
pc.printf("token = %s\n", token);
token = strtok(NULL, ",;");
pc.printf("token = %s\n", token);
a = atoi(token);
token = strtok(NULL, ",;");
pc.printf("token = %s\n", token);
b = atoi(token);
token = strtok(NULL, ",;");
pc.printf("token = %s\n", token);
c = atoi(token);
pc.printf("a=%d; b=%d; c=%d\n", a, b, c);
}
Output
input = [MAN],0,50,50; token = [MAN] token = 0 token = 50 token = 50 a=0; b=50; c=50
