• Volatile. This keyword is needed so as to create volatile objects. These volatile objects have the ability to get modified in the unknown or unmentioned method through hardware.
• auto. This keyword is used to declare the automatic variables. Example: auto int v1; This particular definition means that v1 is considered to be the variable of class type storage and data type of int.
• char. char keyword is used to declare the character variable. Variables that are of type char are of 1-byte length. They can get signed (it is by default unless we use the compiler option ‘-funsigned-char’ or ‘unsigned’), which implies they have got a range of -128 to 127 and 0 to 255, respectively.
• double and float. Both keywords double, as well as float, are needed for declaration of floating type variables. Popular Course in this category.

• const. We van declare an identifier to be constant through the usage of the const keyword. Example: const int r = 5;
• if and else. We use if and else so as to make decisions in C programming. Example: if(a==1) printf(“ a is 1.”); else. printf(“ a is not 1.”); In case the value of a is other than 1,
• break and continue. The break statement would make the program jump out of the most inner and enclosing loop in an explicit manner. The continue is used for statements skipping certain statements that are inside the loop.
• enum. In C programming enumeration types get declared through keyword enum. Example: enum deck { kings; queens; jokers; }; In this example, an enumerated variable deck is created by having the tags: kings, queens, and jokers.
• extern. The extern keyword indicates that the identifier has benn defined somewhere else. It also indicates that in fact storage as well as the initial value, or function body has been defined somewhere else, mostly in the separate module.
• return. Return is used for exiting the function. It would exit from the current function that is executing immediately and return to the calling routine.
