10th Class Computer Chapter 2 Important Questions Notes

  • We need a way to provide input and show output while writing programs. Each programming language has its keywords or standard built-in function for I/O operations.
  • printf is a built-in function in the C programming language. Its name comes from “print formatted” which is used to show the formatted output on the screen.
  • Format specifiers are used to specify the format of data type during input and output operations. The format specifier is always preceded by a percentage (%) sign.
  • scanf is a built-in function in C language that takes input from the user into the variables
  • getch() function is used to read a character from the user. This function accepts characters only. The character entered by the user does not get displayed on the screen.
  • A statement terminator is an identifier for the compiler which identifies the end of a statement. In C language semicolon () is used as a statement terminator.
  • The escape sequence forces printf to escape from its normal behavior. It is the combination of an escape character() and a character associated with special functionality.
  • Escape sequence In specifies the movement of the cursor to the start of the next line. This escape sequence is used to display the output on multiple lines.
  • Escape sequence \t specifies the movement of the cursor to the next tab stop horizontally. A tab stop is a collection of 8 spaces.
  • Basic operators are arithmetic operators, assignment operators, relational operators, and logical operators.
  • Arithmetic operators Arithmetic operators are used to perform arithmetic operations on data to evaluate arithmetic functions. Arithmetic operators are +, -, *,/, %.
  • The modulus operator is also a binary operator, which performs the division of the left operand to the right operand and returns the remainder value after division. The modulus operator works on integer data types.
  • Relational operators compare two values to determine the relationship between values.
  • The logical operator performs an operation on Boolean expressions and returns a Boolean value as a result.
  • The logical AND operator returns true when the result of expressions on both sides is true whereas the Logical OR operator returns true when either of the two expressions is true.
  • The logical NOT operator returns true if the expression is false and vice versa.
  • Short-circuiting is to deduce the result of an operation without computing the whole expression.
  • There are three types of operators. Unary, binary, and ternary operators require one, two, and three operands respectively, to perform the operation.
  • Precedence tells which operation should be performed first. Different operators have different precedence. Operators with higher precedence are evaluated first and the ones with lowest precedence are evaluated last.

Define These Term:

  • Statement Terminator
  • scanf
  • Modulus Operator
  • Format Specifier
  • Escape Sequence
