You do not require to develop integers for the majority of applications. Nevertheless, They're sometimes accustomed to optimise sub-location functions. After we subset a knowledge body or matrix, we are interacting with C code so we is likely to be tempted to utilize integers with the purpose of rushing up our code. One example is, if we think about the arguments for the head perform
