Can you return a char in C++?

While you cannot return a char[], you can do this (with pointers.) An approach which is used by some C library functions, e.g. strcpy, strcat, (i.e. they return a pointer to the buffer you gave them in the first place.) void Xout( char * message, int length);

How do you return a string in C?

Strings in C are arrays of char elements, so we can’t really return a string – we must return a pointer to the first element of the string. All forms are perfectly valid. Note the use of const , because from the function I’m returning a string literal, a string defined in double quotes, which is a constant.

What is return type in C?

Return Type − A function may return a value. The return_type is the data type of the value the function returns. Some functions perform the desired operations without returning a value. In this case, the return_type is the keyword void.

How to free memory from char array in C?

How to return a pointer to an array in C?

Since arr+i points to i th element of arr,on dereferencing it will get i th element of arr which is of course a 1-D array.

We know,the pointer expression*(arr+i) is equivalent to the subscript expression arr[i].

To access an individual element of our 2-D array,we should be able to access any j th element of i th 1-D array.
