Array of chars in C++ programming language
String is a sequence of characters. char data type is used to represent one single character in C++. So if you want to use a string in your program then you can use an array of characters. The declaration and definition of the string using an array of chars is similar to declaration and definition of an array of any other data type:
Any string ends with a terminating null character '\0'. An array definition in such a way should include null character '\0' as the last element. In above case the capacity of an array is 10 but we have used only 8 of it. The remaining two chars of an array will not be defined.
//define an array of chars with 10 elements
char msg[10] = { 'H', 'A', 'P', 'P', 'Y', 'G', 'O', '\0' };
As the name already suggests, these operators help in assigning values to variables. These operators help us in allocating a particular value to the operands. The main simple assignment operator is '='. We have to be sure that both the left and right sides of the operator must have the same data type. We have different levels of operators. Assignment operators are used to assign the value, variable and function to another variable. Assignment operators in C are some of the C Programming Operator, which are useful to assign the values to the declared variables. Let's discuss the various types of the assignment operators such as =, +=, -=, /=, *= and %=. The following table lists the assignment operators supported by the C language:
The C++ comments are statements that are not executed by the compiler. The comments in C++ programming can be used to provide explanation of the code, variable, method or class. If we write comments on our code, it will be easier for us to understand the code in the future. Also, it will be easier for your fellow developers to understand the code. By the help of comments, you can hide the program code also. There are two types of comments in C++: • Single Line comment. • Multi Line comment
An array is defined as the collection of similar type of data items stored at contiguous memory locations. Arrays are the derived data type in C++ programming language which can store the primitive type of data such as int, char, double, float, etc. It also has the capability to store the collection of derived data types, such as pointers, structure, etc. The array is the simplest data structure where each data element can be randomly accessed by using its index number. C++ array is beneficial if you have to store similar elements. For example, if we want to store the marks of a student in 6 subjects, then we don't need to define different variables for the marks in the different subject. Instead of that, we can define an array which can store the marks in each subject at the contiguous memory locations.
What are "Constants"? Constants refer to as fixed values, unlike variables whose value can be altered, constants -- as the name implies does not change, they remain constant. And
C++ Program to check whether an undirected graph contains "Eulerian Cycle". The criteran Euler suggested, If graph has no odd degree vertex, there is at least one eulerian circuit. If
In this program, "enter the size "of 2 matrix at first. To multiply two matrices, the number of columns of first matrix should be equal to the "number of rows" to second matrix. C++ Code
Matrix addition is the "operation of adding" 2 matrices by adding the corresponding entries together. 2 dimensional array, represented in the form of "rows and columns", also suitable
