c - How can you split such complex strings

Question

INPUT :

A string in c that looks like this : " 12345 computer seince 101"

OUTPUT:

NUMBER OF COURSE = "12345"

NAME OF COURSE = "computer seince 101"

i need to ignore all spacebars before the number and the name, so strings like : "(spaces)12345(more spaces)computer sience 101" are allowded

i tried messing around with strtok, but i failed

Answer 1

Use strtol() function.

#include <stdio.h>
#include <stdlib.h>

int main () {
   char str[30] = " 12345 computer science 101";
   char *ptr;
   long ret;

   ret = strtol(str, &ptr, 10);
   printf("NUMBER OF COURSE %ld
", ret);
   printf("NAME OF COURSE %s", ptr);

   return(0);
}

The output is:

NUMBER OF COURSE 12345
NAME OF COURSE  computer science 101
