Say you have the argument to main in the form of ./program 447 758. How would the separation of those two numbers into integers be done for example to gain the result of.
Its driving me mad, i know its simple but can't seem to grasp it. Actual code would be extremely appreciated. ThanksCode:first_num[0] = 4;
first_num[1] = 4;
first _num[2] = 7;
second_num[0] = 7;
second_num[1] = 5;
second_num[2] = 8;
For starters try to come up with an algorithm for doing this task, coding it will become a lot simpler afterwards.
those argurment are string already
argv[1][0] will be 4 argv[1][2] will be 7 and so on
actually it will be '4', '7' etcQuote:

The numeric value of each character will be the '4' and '7'. To make that into an integer, one needs to subtract the value of '0'.

well, thats what i said in my first post ...
not even closeQuote:

Solved, i stumbled upon this
C: How can I split a number into digits? - Yahoo! Answers
and then did this
I hope someone who has the same problem comes across this :)Code:#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX 5
int main (int argc, char *argv[])
{
int val;
int whole1; /*stores the whole number*/
int seperated_whole1[MAX];/*seperate digits of whole1*/
int i = MAX - 1;/*for use in the seperation loop*/
whole1 = atoi(argv[1]);
/*
*This loop splits the whole1 integer into seperate digits for the array in preperation for
*individual manipulation
*/
while (whole1 > 0)
{
seperated_whole1[--i] = whole1 % 10;
whole1 /= 10;
}
printf("%d %d %d %d\n", seperated_whole1[0], seperated_whole1[1], seperated_whole1[2], seperated_whole1[3]);
return 0;
}
