how can I find the largest number from three numbers

Answer 1

int a,b,c,grt;

((a>b)&&(a>c))?grt=a:(b>c)?grt=b:grt=c;

Answer 2

If there are 3 ints a, b and c.. Then
return max(a, max(b, c)) ;
Will give you the result you seek

You'll have to include the algorithm header too to use the max function ( #include <algorithm>)

Answer 3

if(a>=b && a>=c)
cout<<"a is largest ";
else if(b>=a && b>=c)
cout<<" b is largest ";
else
cout<<"c is largest";

Answer 4

A "cleaner" alternative:

#include <algorithm>

... then in code...
std::max(a, std::max(b,c));

It's still quite short and most directly expresses your intent.

Answer 5

#include <iostream>
using namespace std;

int main() {

//Set the numbers
int a = 8;
int b = 8;
int c = 13;

//Comparing a
if (a > b && a > c) {
cout<<"a("<<a<<") is the greatest number."<<endl;
}
else {
if (a == b) {
cout<<"a("<<a<<") equals to b."<<endl;
}
if (a == c) {
cout<<"a("<<a<<") equals to c."<<endl;
}
}

//Comparing b
if (b > a && b > c) {
cout<<"b("<<b<<") is the greatest number."<<endl;
}
else {
if (b == a) {
cout<<"b("<<b<<") equals to a."<<endl;
}
if (b == c) {
cout<<"b("<<b<<") equals to c."<<endl;
}
}

//Comparing c
if (c > a && c > b) {
cout<<"c("<<c<<") is the greatest number."<<endl;
}
else {
if (c == b) {
cout<<"c("<<c<<") equals to b."<<endl;
}
if (c == a) {
cout<<"c("<<c<<") equals to a."<<endl;
}
}

return 0;
}

Answer 6

function max(a, b) {

(a >= b)
return

;

return b;
}
