C functions are akin to the subroutines of Fortran or the procedures of Pascal. A definition is a special type of declaration. A variable definition sets aside storage and possibly initializes it, a function definition provides its body. An implementation of C providing all of the standard library functions is called a hosted implementation.
The loop counter is used to decide when the loop should terminate and for the program flow to continue to the next instruction after the loop. A common identifier naming convention is for the loop counter to use the variable names i , j , and k (and so on if needed), where i would be the most outer loop, j the next inner loop, etc.
In computer science, a continuation is an abstract representation of the control state of a computer program.A continuation implements the program control state, i.e. the continuation is a data structure that represents the computational process at a given point in the process's execution; the created data structure can be accessed by the programming language, instead of being hidden in the ...
A neighborhood of a point c is a set that contains, at least, all points within some fixed distance of c. Intuitively, a function is continuous at a point c if the range of f over the neighborhood of c shrinks to a single point () as the width of the neighborhood around c shrinks to zero.
Chicken Scheme compiler, a Scheme to C compiler that uses continuation-passing style for translating Scheme procedures into C functions while using the C-stack as the nursery for the generational garbage collector; Kelsey, Richard A. (March 1995). "A Correspondence between Continuation Passing Style and Static Single Assignment Form".
The MISRA C 2004 standard bans goto, continue, as well as multiple return and break statements. [21] The 2012 edition of the MISRA C standard downgraded the prohibition on goto from "required" to "advisory" status; the 2012 edition has an additional, mandatory rule that prohibits only backward, but not forward jumps with goto.

With arbitrary-precision arithmetic, this loop would continue until the computer's memory could no longer hold i. If i was a signed integer, rather than an unsigned integer, overflow would be undefined. In this case, the compiler could optimize the code into an infinite loop.
