The method of function calling in C++ is no different from that in C language. Function calling is still implemented by executing the function calling statement in the caller function.
Below, we take question 1031 in the training ground as an example to show you how to use function calls and parameter passing in C++.
1031 is titled String Reverse Order Problem, the code is as follows:
#include<iostream>#include<cstring>usingnamespacestd;intReverse(chara[],charb[]){inti=0,n;n=strlen(a);while(a[i]!=' '){ b[ni-1]=a[i];i++;}b[n]=' ';return0;}intmain(){charstr1[100];charstr2[100];cin>>str1;Reverse(str1 ,str2);cout<<str2<<endl;return0;}The custom function in this code has two formal parameters, both of which are array types. Two arrays need to be passed in to realize mutual communication between functions. Please read the code carefully and use this program to quickly master the function calling method of C++ and personally Type the code on the computer and submit it for approval!
