Question

Write a program using loop statement that can print all small and capital letters in reverse order.​

Answer 1

Explanation:

#include <stdio.h>

int main() {

char c;

for (c = 'A'; c <= 'Z'; ++c)

print ("%c ", c);

return 0;

}

In this program, the for loop is used to display the English alphabet in uppercase.

Here's a little modification of the above program. The program displays the English alphabet in either uppercase or lowercase depending upon the input given by the user.

#include <stdio.h>

int main() {

char c;

printf("Enter u to display uppercase alphabets.\n");

printf("Enter l to display lowercase alphabets. \n");

scanf("%c", &c);

if (c == 'U' || c == 'u') {

for (c = 'A'; c <= 'Z'; ++c)

printf("%c ", c);

} else if (c == 'L' || c == 'l') {

for (c = 'a'; c <= 'z'; ++c)

printf("%c ", c);

} else {

printf(" rror! You entered an invalid character.");

}

return 0;

}

output

Enter u to display uppercase alphabets.

Enter l to display lowercase alphabets. l
