常用scanf和printf格式码

#include <stdio.h>int main(){int i;long l;unsigned long ul;float f;double d;char c;char s[10];printf("input a char:\t");scanf("%c", &c);printf("c = %c\n", c);printf("input a string:\t");scanf("%s", s);printf("s = %s\n", s);printf("input a int(-2147483647~2147483647):\t");scanf("%d", &i);printf("&i = %x\n", &i);printf("i = %d\n", i);printf("i = 0%o\n", i);printf("i = 0x%x\n", i);printf("input a long(-2147483647~2147483647):\t");scanf("%ld", &l);printf("l = %ld\n", l);printf("input an unsigned long(0~4294967295):\t");scanf("%lu", &ul);printf("ul = %lu\n", ul);printf("input a float:\t");scanf("%f", &f);printf("f = %f\n", f);printf("input a double:\t");scanf("%lf", &d);printf("d = %.8f\n", d);}
