In this example, we will try to pass a string into the function using pointers. The drill for coding is the same as before starting, from changing the function declaration. Instead of passing an array of characters, we will pass a string pointer. That way, the string’s address will be ...
Pass an empty array [] as the argument. Use the libpointer function: p = libpointer; % no arguments p = libpointer('string') % string argument p = libpointer('cstring') % pointer to a string argument Use the libstruct function: p = libstruct('structtype'); % structure type Empty...
Passing String Pointers to a FunctionLet us have a look at another example, where we will pass string pointers to a function.ExampleIn this program, two strings are passed to the compare() function. A string in C is an array of char data type. We use the strlen() function to find ...

returnType functionName(parameter1, parameter2, parameter3) { // code to be executed}In the example below, the function takes a string of characters with name as parameter. When the function is called, we pass along a name, which is used inside the function to print "Hello" and the nam...
In C, as string is an array of char data type. We use strlen() function to find the length of string which is the number of characters in it.ExampleOpen Compiler #include <stdio.h> #include <string.h> int compare( char *, char *); int main() { char a[] = "BAT"; char b[...

How to pass string to matlab function in C programsHave no idea about it, I just edit it.An mxArray can also contain a string. An mxArray is a structure that wraps everything (nicely?):
After inserting the necessary headers and declaring the destination array, we call the strcpy() function and pass it as input arguments in “s2”, the explicit string that we want to copy. In this case, the classic phrase “Hello World” and the destination string dest in “s1”. Here is...
