MHB Tomato or Potato? Output Comparison

AI Thread Summary
When two strings are compared using relational operators in C++, they are evaluated lexicographically based on the ASCII values of their characters. In the provided example, if "tomato" is entered first and "potato" second, the output will be "potato" followed by "tomato" because "potato" is lexicographically greater than "tomato". Similarly, when comparing "aabaa" and "aaaza", "aabaa" is considered less than "aaaza" because the comparison starts from the first differing character, where 'b' in "aabaa" has a lower ASCII value than 'z' in "aaaza". Thus, the output will be "aabaa" followed by "aaaza". This understanding of string comparison is crucial for correctly predicting outputs in C++ programming.

If “tomato” get entered first and “potato” get input afterward, what will the output be?

Code:
string input1;
string input2;

cin>>input1;
cin>>input2;

if (input1 < input2) {
	cout<<input1<<endl;
	cout<<input2<<endl;
}
else {
	cout<<input2<<endl;
	cout<<input1<<endl;
}

First, when composing a post, you will notice a toolbar directly above the text area, and in this toolbar is a button that will generate [CODE][/CODE] tags:

View attachment 5298

You can either click that button first, and then paste your code in between them, or you can paste your code into the post content, then select your code, and click the button to have the selected text wrapped with the tags.

This makes your source code stand out and easier to read since white space is preserved, allowing the indentation to be retained. Please edit your post to add these tags. ;)

Okay, when 2 strings are being compared using the relational operators, how exactly are they being compared? For example, can you tell me which of the following two strings is the greater in such a comparison?

  • aabaa
  • aaaza

Thread 'Star maps using Blender'
Blender just recently dropped a new version, 4.5(with 5.0 on the horizon), and within it was a new feature for which I immediately thought of a use for. The new feature was a .csv importer for Geometry nodes. Geometry nodes are a method of modelling that uses a node tree to create 3D models which offers more flexibility than straight modeling does. The .csv importer node allows you to bring in a .csv file and use the data in it to control aspects of your model. So for example, if you...
I tried a web search "the loss of programming ", and found an article saying that all aspects of writing, developing, and testing software programs will one day all be handled through artificial intelligence. One must wonder then, who is responsible. WHO is responsible for any problems, bugs, deficiencies, or whatever malfunctions which the programs make their users endure? Things may work wrong however the "wrong" happens. AI needs to fix the problems for the users. Any way to...
