Parses the C-string str interpreting its content as an integral number
If the converted value would be out of the range of representable
values by an int, it causes undefined behavior.
/* atoi example */
#include <stdio.h> /* printf, fgets */
#include <stdlib.h> /* atoi */
int main ()
{
int i;
char buffer[256];
printf ("Enter a number: ");
fgets (buffer, 256, stdin);
i = atoi (buffer);
printf ("The value entered is %d. Its double is %d.\n",i,i*2);
return 0;
}
/* Output */
Enter a number: 73
The value entered is 73. Its double is 146.
