How to convert char value into integer value in c programming

Individual characters are integers

Code:

#include <stdio.h>



char    c = 'A';



main    ()

{

        printf ("%d\n", c);

}

Strings are not and you need to use a function to convert "12345" to 12345:

Code:

#include <stdio.h>

#include <stdlib.h>



char    *string = "12345";



main    ()

{

        printf ("%d\n", atoi (string));

}

Welcome!
Will this help you;

Code:

 

#include <string.h>

#include <stdio.h>

int main()

{

char szTemp[10];

int nNumber = 0;

strcpy(szTemp, "10"); 

// Convert the string to number.

nNumber = atoi(szTemp);

printf("The converted number is : %d \n",nNumber);

return 0;

}

Also I've found this site while searching a little,it has some nice things.Anyway you could search yourself a little,because there are so many guides,tutorials and books about C on the net that will help you understand C much better and we have Programming forum here,so you could've started your thread there and searched it a little too.
