abstract = {We demonstrate that the $\mathcal{C}-$class functions, pair $(h,f)$ upper-class functions, cone $\mathcal{C}-$class functions, $1-1-$ up-class functions, multiplicative $\mathcal{C}-$class functions, inverse$-\mathcal{C}-$class functions, $\mathcal{C}_{F}-$simulation functions, $\mathcal{C}^{*}-$class functions are powerful and fascinating weapons for the generalization, improvement, and extension of considerable conclusions obtained in the fixed point theory. Towards the end, we point out some open problems whose answers could be interesting.},
