Thread: C++ task

Hello, I have a task in C++:
My task is: Create a zoo structure to represent animals at a zoo. Let the structure contain the following data: number (integer), name, weight (in kilograms). Declare an array with three elements of the described zoo structure and test the following functions. Create the following features:
• Function animal_create by which the keyboard is entered: number, name, weight(0.5 t)
• Function output_animal to derive animal data
• Function double_weight that doubles the weight of all animals
What I have tried: view in file or:

[COLOR=#24292F][FONT=-apple-system]

Code:

#include<iostream>
#include<windows.h>
#include<iomanip>
#include<string.h>
using namespace std;

struct zoo{
	int number;
	char name [30];
	double kg;
	char push_back [30];
};

void animal_create (zoo[]){
	cout<<"Number: ";
	cin>>zoo.number;
	cout<<"Name: ";
	cin>>zoo.name;
	cout<<"Weight: ";
	cin>>zoo.kg;	
}

void output_animal(zoo[]){
	cout<<"Number "<<setw(10)<<"Name "<<setw(10)<<"Weight "<<"\n";
	cout<<zoo.number<<" "<<zoo.name<<" "<<zoo.kg<<"\n";
}

void double_weight(zoo[]){
	int i;
	for(int i=0; i<3; i++){
		zoo[i].kg=zoo.kg*2;
	}
}

int main(){
	cout<<"Add animal: ";
	cin>>zoo.push_back;
	cout<<"Enter data: ";
	int j;
	for(int j=0; j<3; j++)
	animal_create(zoo[i]);
	return 0;
}

Your functions needed variable names as well as types.

Tip: Paste the requirements as comments in the code.
Tip: Make sure simple input and output work before trying to write data manipulation code.

Eg.

Code:

#include<iostream>
#include<iomanip>
using namespace std;
 
struct zoo{
    int number;
    char name [30];
    double kg;
};

// Function animal_create by which the keyboard is entered: number, name, weight(0.5 t)
void animal_create (zoo &creature){
    cout<<"Number: ";
    cin>>creature.number;
    cout<<"Name: ";
    cin>>creature.name;
    cout<<"Weight: ";
    cin>>creature.kg;  
}
 
// Function output_animal to derive animal data
void output_animal(zoo &creature){
    cout<<"Number "<<setw(10)<<"Name "<<setw(10)<<"Weight "<<"\n";
    cout<<creature.number<<" "<<creature.name<<" "<<creature.kg<<"\n";
}

// Function double_weight that doubles the weight of all animals
 
int main(){
    // Declare an array with three elements of the described zoo structure
    zoo myZoo[3];
    for(int j=0; j<3; j++)
        animal_create(myZoo[j]);
    for(int j=0; j<3; j++)
        output_animal(myZoo[j]);
    return 0;
}
