C++ program to find out the smaller number from given numbers

#include<iostream>
#include<conio.h>

int main(void)
{

    int a,b,c,min;

    std::cout<<"Enter the value of a = ";
    std::cin>>a;
    std::cout<<"Enter the value of b = ";
    std::cin>>b;
    std::cout<<"Enter the value of c = ";
    std::cin>>c;

    if(a<b)
        if(a<c)
            min = a;
    if(b<a)
        if(b<c)
            min = b;
    if(c<a)
        if(c<b)
            min = c;

    std::cout<<"The Smaller number is = "<<min;

return 0;
}

Enter the value of a = 5
Enter the value of b = 3
Enter the value of c = 1
The Smaller number is = 1
