C Programming: Convert a string to lowercase
C String: Exercise-22 with Solution
Write a program in C to convert a string to lowercase.
Sample Solution:
C Code:
#include<stdio.h>
#include<ctype.h>
int main() {
int ctr = 0; // Variable to keep track of position in the string
char str_char; // Variable to store each character of the string
char str[100]; // Array to store the input string
printf("\n Convert a string to lowercase :\n");
printf("----------------------------------");
printf("\n Input a string in UPPERCASE : ");
fgets(str, sizeof str, stdin); // Read a string including spaces from the user
printf(" Here is the above string in lowercase :\n ");
while (str[ctr]) { // Loop through each character of the string until the null character is encountered
str_char = str[ctr]; // Retrieve each character from the string
putchar(tolower(str_char)); // Convert the character to lowercase using tolower() function and print it
ctr++; // Move to the next character in the string
}
return 0; // Return 0 to indicate successful execution of the program
}
Sample Output:
Convert a string to lowercase : ---------------------------------- Input a string in UPPERCASE : THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG. Here is the above string in lowercase : the quick brown fox jumps over the lazy dog.
