# Convert Integer to Char in C

This tutorial introduces how to convert an integer value into a character value in C. Each character has an ASCII code, so it’s already a number in C. If you want to convert an integer to a character, simply add `'0'`.

## Add `'0'` to Convert an `int` to `char`

The `'0'` has an ASCII value of 48. so, we have to add its value to the integer value to convert it into the desired character. The program is as below:

``````#include<stdio.h>
int main(void)
{
int number=71;

char charValue = number+'0';
printf("The character value is :%c",charValue);

return 0;
}
``````

Output:

``````The character value is: w
``````

Below is a program that will convert an integer to the character only between 0 to 9.

``````#include<stdio.h>
int main(void)
{
int number=7;
char charValue=number+'0';
printf("The value is :%c",charValue);
return 0;
}
``````

Output:

``````The value is: 7
``````

Another program to convert an integer value to a character is as below:

``````#include<stdio.h>

int main(void)
{
char charValue[] = "stringValueX";
int anyNumber;
for (anyNumber= 0; anyNumber< 10; ++anyNumber)
{
charValue = anyNumber+ '0';
puts(charValue);
}
return 0;
}
``````

Output:

``````stringValue0
stringValue1
stringValue2
stringValue3
stringValue4
stringValue5
stringValue6
stringValue7
stringValue8
stringValue9
``````

## Assign an `int` Value to `char` Value

Another way to convert an integer value to a character value is to assign an integer value to a character value as below: The character value corresponding to an integer value is printed here.

``````#include<stdio.h>

int main(void)
{
int number = 65;
char charvalue = number;

printf("The character value :%c", charvalue);

return 0;
}
``````

Output:

``````The character value : A
``````

Below is another way to convert an integer value to a character value. Here, the value is typecasted, so the value 67 gets converted into the corresponding ASCII value.

``````#include<stdio.h>
int main(void)
{
int number = 67;
char charValue = (char)number;
printf("The character value = %c", charValue);

return 0;
}
``````

Output:

``````The character value = C
``````

## `sprintf()` Function to Convert an Int to a Char

The `sprintf()` function works the same as the `printf()` function but instead of sending output to console, it returns the formatted string.

The first argument to the `sprintf()` function is a pointer to the target string. The remaining arguments are the same as for the `printf()` function.

### Syntax of `sprintf()`

``````int sprintf(char *strValue, const char *format, [arg1, arg2, ... ]);
``````
• `strValue` is a pointer to the char data type.
• `format` is used to display the type of output along with the placeholder.
• `[arg1,arg2...]` are the integer(s) to be converted.

The function writes the data in the string pointed to by `strValue` and returns the number of characters written to `strValue`, excluding the null character. The return value is generally discarded. If any error occurs during the operation, it returns `-1`. The program to convert an integer to a character is as below:

``````#include<stdio.h>
int main(void)
{
int number = 72;
char charValue;

sprintf(charValue, "%c", number);
printf("The character value = %s", charValue);

return 0;
}
``````

Output:

``````The character value = H
``````
