Write a C program that reads in a lowercase character, converts it to uppercase and then displays the uppercase equivalent
C program that converts lowercase character to its uppercase equivalent and displays it
Explanation
Step 1: Read the lowercase character
Step 2: Convert the lowercase character to its uppercase by using the library function toupper()
Step 3: Display the converted uppercase character
Note:
The function toupper() used in this program is a library function which is generally included in the header file ctype.h and the purpose of this function is to convert the lowercase letter to its uppercase.
#include<stdio.h>
#include<ctype.h>
void main()
{
char lower, upper;
lower = getchar();
upper = toupper(lower);
putchar(upper);
}
Output:
l L
#include
#include
void main()
{
char ch;
clrscr();
printf(“Enter a Character”);
scanf(“%c”,&ch);
if(ch>=65 && ch<=90)
ch=ch+32;
ch=ch-32;
printf("your changed character =%c",ch);
getch();
}
/* WAP to change case of a character*/
#include
#include
void main()
{
char ch;
clrscr();
printf(
lower = getchar();
This line returns a character you entered and it may not be a lowercase letter. It can be any character you inputted.
