The role of conditional statements is really important. They allow your program to evaluate conditions and execute specific code based on the outcomes. These conditions might involve user input, data comparisons, or even external factors. Without conditional statements, your code would be rigid and unable to adapt to changing circumstances.

These conditional statements create branches in the code. Depending on the conditions, the program can follow different paths or branches, allowing for non-linear program execution. All of this is achieved by using special built-in commands, such as if, else if, else, switch. These commands allow the program to assess logical conditions and act accordingly.
