In a basic calculator program, users can choose an operation by entering a number, and the program responds accordingly: int choice; printf("Select operation:\n1. Addition\n2. Subtraction\n3. Multiplication\n4. Division\n"); scanf("%d", &choice); switch (choice) { case 1: // Perform ...

C If Else statement is kind of an extension toC IfStatement. In C If statement, we have seen that execution of a block of statements depends on a condition. In If Else statement, we have one more block, called else block, which executes when the condition is false. So, in C if-else...

character is a capital letter, then the output is also formatted in capital letters. For example, if the format specifier is%Finstead of%f, an infinity is formatted asINFinstead ofinf. Thescanffunctions can also parse these strings, so these values can make a round trip throughprintfan...
