JSON is described best here: http://www.json.org/ It's like XML, but fat-free. You use it to move data around, store things, or just generally represent your program's state. As a library, cJSON exists to take away as much legwork as it can, but not get in your way. As a...
Here are some type and variable declarations in C syntax: typedef struct int x; char y; Rec1; typedef Rec1 Rec2; typedef struct int x; char y; Rec3 Rec1 a,b; Rec2 c; Rec3 d; State which variables What is C++? Discuss how local declarations are stored in compute...
What is the meaning of typedef? The typedef isa keyword used in C programming to provide some meaningful names to the already existing variable in the C program. It behaves similarly as we define the alias for the commands. In short, we can say that this keyword is used to redefine the ...
