What is String

In C programming, a string is a sequence of characters terminated with a null character \0.

For examples:

char str[] = "Topperworld\0";                                                                                                                                              

When the compiler encounters a sequence of characters enclosed in the double quotation marks, it appends a null character \0 at the end by default.

Declaring a String in C :

A String in C is an array with character as a data type. C does not directly support string as a data type, as seen in other programming languages like C++. Hence, character arrays must be used to display a string in C. The general syntax of declaring a string in C is as follows:


char variable[array_size];


char str[5];
char str2[50];
