C ++浮点到整数类型转换 [英] C++ floating point to integer type conversions

问题描述

在C ++中，用于将浮点数据类型转换为整数的不同技术有哪些？

What are the different techniques used to convert float type of data to integer in C++?

#include<iostream>
using namespace std;
struct database
{
    int id,age;
    float salary;
};
int main()
{
    struct database employee;
    employee.id=1;
    employee.age=23;
    employee.salary=45678.90; 
    /*
    How can i print this value as an integer
    (with out changing the salary data type in the declaration part) ?
    */
    cout<<endl<<employee.id<<endl<<employee.age<<endl<<employee.salary<<endl;
    return 0;
}
