小弟初学C语言，有一程序，望大家指导:(求n年后本息和) 希望能指出所有错误，十分感谢！

Question

#include<stdio.h>
#include<math.h>
void main()
{
double i,j,b;
printf("How much would you like to deposit?\n");
scanf("%f",&i);
printf("Investment period in years:\n");
scanf("%f",&j);
b=i*pow(1.01,j);
printf("%f\n",b);
}

Answer 1

double类型的，要在scanf里面不能用“%f”，要不然会得不出结果，要用“%lf”

Answer 2

//double需要%lf
#include<stdio.h>
#include<math.h>
void main(){
double i,j,b;
printf("How much would you like to deposit?\n");
scanf("%lf",&i);
printf("Investment period in years:\n");
scanf("%lf",&j);
b=i*pow(1.01,j);
printf("%lf\n",b);
}
