Printing range of numbers and adding intervals

[niirex1]

I want to print a rang of numbers according to the intervals between them.
E.g minimum: 3, maximum: 12 and the interval is 3 should print something like 3,6,9,12.
However, i am struggling with the needed logic to achieve this aim.

Kindly assist

  #include <iostream>
using namespace std;

int main(int argc, const char * argv[]) {
    int min, max, intvr,add;

    cout<<"This program prints out the minimum, maximum and interval values"<<endl;
    cout<<endl;
    cout<<"enter mininum number: ";
    cin>>min;
    cout<<"enter maximum number: ";
    cin>>max;
    cout<<"enter interval number: ";
    cin>>intvr;
    cout<<endl;

    
   
    
    for(add=min; add<max; ++add)
    {
        cout<<add+intvr;
    }
cout<<endl;
}

In the example with max=12, you want to print the maximum value, so the condition should be add<=max. Also be sure to print a space after each value. I would change the for loop so that it iterates the actual values:

for (int val=min; val<=max; val+= intvr) {
    cout << val << ' ';
}

I think the pseudocode would be something like this:
-Get minimum number
-Get maximum number
-Get interval
-number is minimum
-As long as number is lower or equal to maximum number
----display number
----increment number by interval

Hope this helps

Edit: The only thing that you need to work on is your for loop I think, nothing big though:

for(add = min; add <= max; add += intvr)
{
    cout << add << ", ";
}

The tutorial http://www.cplusplus.com/doc/tutorial/control/
has section: The for loop

The for loop is designed to iterate a number of times. Its syntax is:

for ( initialization; condition; increase ) statement;

The increase is
* an expression
* executed after the statement (i.e. the body of the loop)

The increase is not limited to be "plus one". Even the example in the tutorial uses "minus one".
