• Background: The conditional operator ?:
– An alternate of simple if-else statement
• Character handling library functions
– Boolean functions of format is<charType>(int)
– Examples
• String format conversion library functions
– Converting from string to numbers
• Formatted read/write in string variables
– The sscanf and sprintf functions

, Conditional Operator
• The only ternary operator in C, i.e. operator with
3 operands.
