Conditional statements in C++

Now, we are going to understand conditional statements in C++. If you have been programming for a while, you might have done some basic programs, like taking some user input, or some operator-related programs. But there is much more than that here.

Conditional statements in CPP

So, now we are going to learn about conditional statements. But first of all, let’s discuss what is the need for conditional statements in our general programming, or in C++.

Many a time, we are required to have conditional statements in our programs, when we need to do something, on the basis of some condition. In our real life as well, we come across some conditions, like if it is cold, wear a sweater. So, wearing a sweater we can say is an action(doing something), but doing something is done on the basis of some condition, like only if it is cold.

Just like this, in our programming as well, we need to do some things on the basis of some conditions. For that, we are going to have a look at some different concepts. Here is the list of the concepts that we are going to cover now –

• if else statements
• if else ladder
• nested if else
• switch case statement

As we move further, we would explore them at an individual level in greater detail, but here is some brief information about the above-stated concepts –

if else statements :

Just like in our real life, we are checking – “if it is cold, then I will wear a sweater, else I will wear a t-shirt. “, so here, we have if else statements. Similarly, in our C++ programs, we can have these if-else statements, to do some things on the basis of some conditions.

If else ladder:

Once you are done learning if-else statements, you would understand that we are checking the condition with an if statement, but not with else. But at times, you might be in some situation, when you need to have some condition even after else. So, in such a situation, you would have another if after else.

Nested if else:

As the name says, here, we are going to have an if block, inside an if block, and this is what we mean by nesting. When you would learn the concept and the need for the concept, you would get the points.

Switch case statement:

The switch case statement is used usually in cases, when we have many cases, and we want to execute something particular on the basis of the matched expression. When you would see this concept in action, you would understand the need and the concept.

So, you can explore these concepts individually at a greater depth, and then use them in action in your C++ programs, as and when required.
