Convert ASCII number to ASCII Character in C

char A;
printf("ASCII value of %c = %d", c, c);

In this program, the user is asked to enter a character. The character is stored in variable c. When %d format string is used, 65 (the ASCII value of A) is displayed. When %c format string is used, A itself is displayed.

Output: ASCII value of A = 65
