g为何输出为 0.000000000000，而不是 0.123456789000

Question

#include<stdio.h>
int main()
{
int a, b;
float d, e;
char c1, c2;
double f, g;
long m, n;
unsigned int p, q;
a = 61; b = 62;
c1 = 'a'; c2 = 'b';
d = 3.56; e = -6.87;
f = 3157.890121; g = 0.123456789;
m = 50000; n = -60000;
p = 32768; q = 40000;
printf("a=%d,b=%d\nc1=%c,c2=%c\nd=%6.2f,e=%6.2f\n", a, b, c1, c2, d, e);
printf("f=%15.6f,g=%15.12f\nm=%ld,n=%ld\np=%u,q=%u\n", f, q, m, n, p, q);

}

Answer 1

printf中的变量写错了，把g写成了q
