What is the difference between if and else if in C?

Question

C programming

Answer 1

"if" is a keyword used to indicate a code block that will only be executed if a certain specified condition is met.

"else" is another keyword that allows a code block to be executed if the condition specified on the "if" statement does not hold.

C allows chaining multiple "if" statements by using the "else if" notation. In an "else if", the code block will be executed if the previous conditions didn't hold, but the current one does.

if (a < b)
printf("Less than\n");
else if (a > b)
printf("Greater than\n");
else
printf("Equal\n");

In other languages, the "else if" may be another different keyword: "elsif" (VHDL) or "elif" (Python).
