在 C 语言中，可以使用 %Lf 格式说明符来使用 scanf 函数为 long double 类型的变量赋值，示例如下：include <stdio.h>int main() { long double num;printf("请输入一个 long double 类型的数: ");scanf("%Lf", &num);printf("您输入的数是: %Lf\n", num);return 0;} ...
Format specifier for double in printf() in C When we use theprintf()function for the floating-point data we can use%ffor both float anddouble, and%Lfforlong double, and we can use%lfalso fordouble. In theprintf(), there is no difference but when we usescanf()function for the floatin...
scanf("%f",&r); ---> scanf("%lf",&r);这儿是原因：Because C will promote floats to doubles for functions that take variable arguments. Pointers aren't promoted to anything, so you should be using %lf or %g to read in doubles....
首先看看scanf：这里明确指出来scanf在读入float和double时标识符都不同。double需要使用lf标识符。实际上...

double in value 在价值上翻一番 double on〔upon〕 迂回,突然袭击 五、用法：1、double用作形容词的基本意思是“双的”,其所修饰的名词一般为单数。2、double常用来表示倍数,后面可接名词、数词、代词,在double与被修饰的名词之间有时还可用定冠词the或物主代词。3、double的基本意思是“对折起来”...
【注意】后面的i,n,k应该是int类型的。include<stdio.h> int main(){ double a[15]={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15},b;//a和b是double类型 int i,n,k;//其他的是int类型 printf("输入一个数\n");scanf("%lf",&b);//这里是%lf for(i=0,n=15,k=0;k<=3...
例如double型的数据为a=5.1413，程序如下：incloud <stdio.h> main( ){ double a；printf("请输入一个double型数据：”）；a= int (a*100+0.5)/100 ；printf("%lf",a)。} 这时候printf输出的结果将是5.14。
