C Interview Question | Difference between else if ladder and switch case in C language | Programming Classes The else-if ladder checks multiple conditions using complex expressions and logical operators, making it flexible for range-based decisions. The switch case compares a single variable with constant values, offering better readability and faster execution, but it does not support complex or range-based conditions. .
