Basic C++ help

The following is code to take 3 input values and determine if they are between 1-25 to satisfy a triangle.

#include <iostream>
using namespace std;

int main ()

{

int v1(0), v2(0), v3(0);


cout << "COMP 160 Eric Tarr" << endl;
cout << "Section 1 450011" << endl;
cout << "Assignment #3 September 17, 2004" << endl << endl;

cout << "This program will determine if three user-entered values satisfy the triangle inequality." << endl << endl;

cout << "Please enter the first input value (between 1 and 25):";
cin >> v1;
cout << endl << endl;
cout << "Please enter the second input value (between 1 and 25):";
cin >> v2;
cout << endl << endl;
cout << "Please enter the third inpute value (between 1 and 25):";
cin >> v3;
cout << endl << endl;

if ( v1 && v2 && v3 >= 1 && v1 && v2 && v3 <= 25)
cout << "The numbers v1, v2 and v3 do satisfy the triangle inequaliy.";

if ( v1 && v2 && v3 < 1 && v1 && v2 && v3 >25)
cout << "The numbers v1, v2 and v3 do not satisfy the triangle inequality.";

else if ( v1 <=1 && v1 <= 25 )
{
cout << "Please enter the first input value (between 1 and 25):";
cin >> v1;
v1 = 1;
}

else if( v2 <=1 && v2 <= 25 )
{
cout << "Please enter the second input value (between 1 and 25):";
cin >> v2;
v2 = 1;
}

else if (v3 <=1 && v3 <= 25 )
{
cout << "Please enter the third input value (between 1 and 25):";
cin >> v3;
v3 =1;
}

return 0;

}


Im to take 3 numbers and print out if they are in range or out of range. If they are out of range im too reset the value to 1 and have the user input another value.

You have said what you need to do and given the code but have made no mention of the problem you have or the question you want answered...

-KM-

I can't get it to output right, If one of the numbers is not in the range I have set then I need the value to reset to 1 and have that number sent back in by the user.

Made some adjustments but still can't get things to print out correctly.


#include <iostream>
using namespace std;

int main ()

{

float v1(0), v2(0), v3(0);


cout << "COMP 160 Eric Tarr" << endl;
cout << "Section 1 450011" << endl;
cout << "Assignment #3 September 17, 2004" << endl << endl;

cout << "This program will determine if three user-entered values satisfy the triangle inequality." << endl << endl;

cout << "Please enter the first input value (between 1 and 25): ";
cin >> v1;
cout << v1;
cout << endl << endl;
cout << "Please enter the second input value (between 1 and 25): ";
cin >> v2;
cout << v2;
cout << endl << endl;
cout << "Please enter the third inpute value (between 1 and 25): ";
cin >> v3;
cout << v3;
cout << endl << endl;

if ( v1 >= 1 && v2 >=1 && v3 >= 1 && v1 <=25 && v2 <=25 && v3 <= 25)

cout << "The numbers v1, v2 and v3 do satisfy the triangle inequaliy.";

else

cout << "The numbers v1, v2 and v3 do not satisfy the triangle inequality.";
cout << endl << endl;

if( 1 < v1 || v1 > 25 )
{
cout << "Please enter the first input value (between 1 and 25):";
cout << v1;
cout << endl;
cout << "The first input value v1 is not greater than or equal to one and less than or equal to 25. Your value has been reset to one." << endl;
v1 = 1;
cin >> v1;
}

else if ( 1 < v2 || v2 > 25 )
{
cout << "Please enter the second input value (between 1 and 25):";
cout << v2;
cout << endl;
cout << "The second input value v2 is not greater that or equal to one and less than or equal to 25. Your value has been reset to one." << endl;
v2 = 1;
cin >> v2;
}

else if( 1 < v3 || v3 > 25 )
{
cout << "Please enter the third input value (between 1 and 25):";
cout << v3;
cout << endl;
cout << "The third in put value v3 is not greater than or equal to one and less than or equal to 25. Your value has been reset to one." << endl;
v3 = 1;
cin >> v3;
}

return 0;

}


1. do I need to use float or int?
2. how do I get the last If statements to print when the values are not in the right range.
3. also how do I get it to print the value in a sentence instead of "v1"

1. use "int"
2. i would use the "switch" statement
3. (<go like this>) cout << " hi my name is the phantom" << v1 << "this is the answer" << endl;
