Today we’ll write a program using Character type data. Character type data is used to assign letters in English language and special symbols like summation (+), substriction (-), multiplication (*) and division (/) and etc. A character type symbol needs a byte to keep in memory.

How to Learn to Code C

The following program is to input and print the first letter of your name. Write the codes and run the program.

Code:

#include <stdio.h>
int main()
{
     char ch;
     printf("Enter the first letter of your name: ");
     scanf("%c", &ch);
     printf("The first letter of your name is: %c\n", ch);
     return 0;
}

Output:

We wrote char as it wanted to input a character type data. For this reason, we wrote %c in the scanf and printf quotation. ( \n ) is for new line.

We can write the program in another way,

Code:

#include <stdio.h>
int main()
{
     char ch;
     printf("Enter the first letter of your name: ");
     ch = getchar();
     printf("The first letter of your name is: %c\n", ch);
     return 0;
}

Output:

Getchar is also a function that can read character type data. In this program , getchar function assigned a character after reading. If we want to keep a character directly in a variable, we’ve to use quotation like char c = 'A';

Now, see the program like this…

Code:

#include<stdio.h>
int main()
{
int num1, num2, value;
char sign;
printf("Please enter a number: ");
scanf("%d", &num1);
printf("Please enter another number: ");
scanf("%d", &num2);
value = num1 + num2;
sign = '+';
printf("%d %c %d = %d\n", num1, sign, num2, value);
value = num1 - num2;
sign = '-';
printf("%d %c %d = %d\n", num1, sign, num2, value);
value = num1 * num2;
sign = '*';
printf("%d %c %d = %d\n", num1, sign, num2, value);
value = num1 / num2;
sign = '/';
printf("%d %c %d = %d\n", num1, sign, num2, value);
return 0;
}
