Let us see the C++ program for finding the length of the string by passing values to the function.
We can also pass a structure to a function in two different ways. These two ways are mentioned below;
- Passing by Value
- Passing by Reference
Passing by Value to the function using structures in C++ (Length of string program)

//Pass by value using structures in C++ #include<iostream> #include<string.h> using namespace std; struct lengthstring { char str[10]; }; int display(struct lengthstring leng) { lengthstring s; int len; cout<<"please enter your desired string"<<endl; cin>>leng.str; len=strlen(leng.str); cout<<"The length of desired string is:"<<len<<endl; } int main() { struct lengthstring s1; display(s1); return 0; } |
Output
please enter your desired string

//Pass by reference using structures in C++ #include<iostream> #include<string.h> using namespace std; struct lengthstring { char str[10]; }; int display(struct lengthstring *leng) { lengthstring s; int len; cout<<"please enter string"<<endl; cin>>leng->str; len=strlen(leng->str); cout<<"The length of string is="<<len<<endl; } int main() { struct lengthstring s1; display(&s1); return 0; } |
Output
please enter your desired string
welcome
The length of your desired string is: 7
