When printing a single character in a C program, must I use "%1s" in the format string? Can I use something like "%c"?

C – Read Single Character using Scanf() So, to read a single character from console, give the format and argument to scanf() function as shown in the following code snippet. char ch; scanf("%c", ch); Here, %c is the format to read a single character and this character is stored in variable ch .
printf("%c\n", string[n-1]);
The single character input/output functions are Getchar () and putchar (). Getchar() is used to get a single character and require key after input. Putchar() is used to put a single character on the standard output device.
yes, %c will print a single char:
printf("%c", 'h'); also, putchar/putc will work too. From "man putchar":
#include <stdio.h> int fputc(int c, FILE *stream); int putc(int c, FILE *stream); int putchar(int c); * fputc() writes the character c, cast to an unsigned char, to stream. * putc() is equivalent to fputc() except that it may be implemented as a macro which evaluates stream more than once. * putchar(c); is equivalent to putc(c,stdout). EDIT:
Also note, that if you have a string, to output a single char, you need get the character in the string that you want to output. For example:
const char *h = "hello world"; printf("%c\n", h[4]); /* outputs an 'o' character */ If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
