![String Declaration in C
String declaration syntax:
char string_name[size];
String declaration example:
char str[5];](https://image.slidesharecdn.com/stringsinc-220619194631-3ab44b59/85/String-In-C-Language-6-320.jpg)
![String Initialization in C
Ways to initialize a string in C:
1. Char str[15] = “Simplilearn”;
2. Char str[ ] = “Simplilearn”;
3. Char str[] = {‘a’, ‘b’, ‘c’, ‘d’,’0’};
