C Programming Conditional Statements Questions
Condition statements in C are used almost in every program written in the C programming language. This is a very important concept and a useful building block of programming construct.
Conditional statements in C Programming are used when we have to execute a statement or set of statements on the basis of occurrences of some condition.
Conditional statements are also known as decision control statements.
Conditional statements are also know known as Jump statements some time because they break the sequential execution of the program.
In C Programming there are following conditional statements.
- IF – Simple If , If-else ,If -else if -else , nested if-else
- Switch Case Statements
- Conditional Operator
- Goto statements
