C String to Int

     

In this section, you will learn how to convert a string represented value into an integer represented value in C. You can see in the given example that we have used the library function atoi() provided by the header file <stdlib.h>, to convert the string value of digits ("100") into int value. The number may consist of an optional sign and a string of digits, then only converted number is returned otherwise 0 is returned. This method can skip the initial whitespace characters like space, tab, new line etc. . 

Here is the code:

 

 

StringToInt.c

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
int main() {
  int i;
  i = atoi("100");
  printf("The integer value is: %d", i);
  getch();
  return 0;
}

Output will be displayed as:

STRING~1.EXE
