© 2020 - EDUCBA. This program will initialize members of a class while declaring array of objects in C++ programming language. The storage size of character data type is 1(32-bit system). // Example to copy a string // Example code to explain valid string declaration using double quotes char *char_ptr = "Look Here" ; This initializes char_ptr to … In this tutorial, you will learn to work with arrays. Note that the final element is the NUL-terminator \0 which the language exploits as an "end of string" marker. “size_str” is the size of the string named as string_name. if(result_compare2 == 0) char string_name[] = “mystring” // this is allowed because string is defined with double quotes, char string_name[] = ‘mystring’ // this is not allowed because string is defined with single quotes. // Example of reading a string using fgets and displaying string using puts // display the concatenated string to … There are different ways to initialize strings in C. Please have a look at below different examples that show different ways to initialize a string in C. Code: End Example const char* str = "This is GeeksForGeeks"; // main function To fix it, use the new function to allocate the memory char* screenReturnValue = new char[screenClassName.size() … // Body of main function puts(first_name);    // displaying string using puts function #include // Example of reading a string using fgets and displaying string using puts ; Identifier - Valid variable name (name of the allocated memory blocks for the variable). char str_cmp3[20]= "my string 3"; // declaration of string str_cmp3 You will learn to declare, initialize and access elements of an array with the help of examples. THE CERTIFICATION NAMES ARE THE TRADEMARKS OF THEIR RESPECTIVE OWNERS. printf("vlaue of str1: = %s \n",str1); // displaying the value of str1 char name1[] = "my example string1"; // string name1 is defined using double quotes which is valid C Arrays. Here please note that the null character “\0” is stored additionally at the end of the string. // main function Start Your Free Software Development Course, Web development, programming languages, Software testing & others. char Variable Declaration and Variable Initialization: Variable Declaration: To declare a variable, you must specify the data type & give the variable a unique name. }, // Example code to understand string functions in C There are three main ways of assigning string constants to string variables. ALL RIGHTS RESERVED. fgets(first_name, sizeof(first_name), stdin);  // reading input string from the user using fgets function We use this with small arrays. char string_name[9] = “mystring”; Initialization vector can be done in many ways. //concatenates str_cat1 and str_cat2 and resultant string is stored in str_cat1. For example, 'A' can be stored using char datatype. So the ASCII value 97 will be converted to a character value, i.e. Dynamic Initialization: Here, the variable is assigned a value at the run time. Some examples of illegal initialization of character array are, { You can also go through our other related articles to learn more –, C Programming Training (3 Courses, 5 Project). int main() The C compiler automatically adds a NULL character '\0' to the character array created. strcat(str_cat1,str_cat2); char last_name[30]; // declaration of last_name string } printf("concatenated data of string is: = %s \n",str_cat1); // displaying the value of str_cat1 Different ways of initializing a variable in C. Method 1 (Declaring the variable and then initializing it) int a; a = 5; Method 2 (Declaring and Initializing the variable together): } char string_name[] = “mystring”; // string assignment to string_name L-prefixed wide string literals can be used to initialize arrays of any type compatible with (ignoring cv-qualifications) wchar_t Successive bytes of the string literal or wide characters of the wide string literal, including the terminating null byte/character, initialize the elements … This indicates the end character of every string.
