Example:
例：
#include <stdio.h>int main(void) {const char1 = 'A';//uppercase alphabetconst char2 = 'X';//uppercase alphabet const char3 = 'a';//lowercase alphabetconst char4 = 'x';//lowercase alphabetconst char5 = '5';//a digitconst char6 = '#';//a special character const char7 = ' ';//a space //print valuesprintf("char1 = %c\n", char1);printf("char2 = %c\n", char2);printf("char3 = %c\n", char3);printf("char4 = %c\n", char4);printf("char5 = %c\n", char5);printf("char6 = %c\n", char5);printf("char7 = %c\n", char7);return 0;}
