31. Training C/C++Ecosoftware 31 6.2 Operators o Bitwise Logical Operators Bitwise Logical Operators AND ( NUM1 & NUM2) Return 1 if both the operands are 1 OR ( NUM1 | NUM2 ) Returns 1 if bits of either of the operand are 1 NOT ( ~ NUM1) Reverses the bits of its operand ( from 0 to 1 and 1 to 0) XOR ( NUM1 ^ NUM2) Returns 1 if either of the bits in an operand is 1 but not both

32. Training C/C++Ecosoftware 32 6.2 Operators o Example Bitwise Logical Operators

45. Training C/C++Ecosoftware 45 8.Array o Introduction Array o One-Dimensional o Multi-Dimensional

46. Training C/C++Ecosoftware 46 8.1 Introduction Array o Each member of an array is identified by unique index or subscript assigned to it. o The dimension of an array is determined by the number of indices needed to uniquely identify each element o An index holds integer values starting with zero o An index is a positive integer enclosed in [ ] placed immediately after the array name

47. Training C/C++Ecosoftware 47 8.2 One-Dimensional o Declaring Array type array-Name[array-size];  int c[12]; // c is array of 12 integers o Init element of array  int c[5] = {}; // init element of integer for 0  int c[5] = {1,3,5,7,10}; // o Interaction with array  Using loop statement : for, while, do-while

48. Training C/C++Ecosoftware 48 Example One-Dimensional

49. Training C/C++Ecosoftware 49 8.3 Multi-Dimensional o Declaring Array type array-Name[array-size];  int c[4][3]; // c is array 2 dimensions of integers o Init element of array  int c[2][2] = {{1,1},2,4}; // init element for array o Using nested loop for interaction with array
