Converting string to number and number to string using C language
Problem
What do you mean by String to number and number to string conversion in C programming language?
Solution
There are two functions available for conversion. They are −
- sscanf() − convert string to number
- sprintf () − used for converting number to string
String to number conversion
We can convert string to number using the sscanf() function −
Syntax
sscanf (string name, “control string”,variable list)
Example
#include<stdio.h>
main (){
char a[20] = “02 01 2010”;
int day, mon, yr;
clrscr();
sscanf (a, “%d%d %d”, &day, &mon, &yr);
printf ( “Day =%d”, day);
printf ( “Month = %d”, mon);
printf ( “Year = %d”, yr);
getch ();
}Output
Day = 02 Month = 01 Year = 2010
Number to string conversion
We can convert string to number using the sprintf() function −
Syntax
sprintf ( string name, “control string”, variable list)
Example
#include<stdio.h>
main (){
char a[50];
int day,mon,yr;
day = 02;
mon = 01;
yr = 2010;
crlscr();
sprintf (a, “%d/%d/%d”, day, mon, yr);
printf ( “today’s date =%s”,a);
getch ();
}Output
Today’s date is 02/01/2010.
