Example

#include <stdio.h>
+ 
+int main(void)
+{
+    puts("Printable ASCII:");
+    for (int i = 32; i < 127; ++i) {
+        putchar(i);
+        putchar(i % 16 == 15 ? '\n' : ' ');
+    }
+}

Possible output:

+
Printable ASCII:
+  ! " # $ % & ' ( ) * + , - . /
+0 1 2 3 4 5 6 7 8 9 : ; < = > ?
+@ A B C D E F G H I J K L M N O
+P Q R S T U V W X Y Z [ \ ] ^ _
+` a b c d e f g h i j k l m n o
+p q r s t u v w x y z { | } ~
