Passing-Strings-To-Function-In-C
INTRODUCTION
Everyone must figure out how to provide a string (character arrays) for a method during this C code. In this case, you execute a method with a text string and then display it in that function.
The procedure that's being utilized during the application is shown below.
void Strfun (char *ptr)
- This function's produce class was void, meaning it would not be returned with anything.
- strfun: The method is called stun.
- *ptr: This character reference, designated as char *ptr, was utilized for recording the initial location of any character array (string) known to be returned by being provided using the main () method.
The statement for calling a function is:
Strfun(buff);
- buff is the character array (string).
Let us look at the example program for passing a string to function in C programming:
/*
Code in C for passing a string to a function.
*/
#include <stdio.h>
void Strfun(char *ptr)
{
printf ("Enter the string that is to be passed: \n%s", ptr);
}
// Let us write the main function.
int main ()
{
// The buffer type is declared as "char" here.
char buff [20] ="Example for passing string to function";
// The main process is seen here.
Strfun(buff);
return 0;
}
The output of the above code is as follows:

Before providing a string for a method, we'll first offer everyone a brief explanation of what strings are. In the C programming language, strings comprise a series of arrays containing letters called the char data structure. You made the statement because it refers to a collection containing letters, since when someone uses kinds:
#include <stdio.h>
void print (char *b)
{
int s = 0;
while (*(b+s))
{
putchar(*(b+s));
s++;}
putchar('\n');}
int main (){
char str [] = "The example for passing string to function";
print(str);
return (0);}
The output of the above program is:

The description of the above program is as follows:
Both application variations use the identical main () method, which accepts a reference that is either a text or a collection of characters as arguments. The functionality was all I had to worry about, which may have contributed to the initial error.
A pointer, char *b, provides the parameter for the print () method. When writing the method, I converted array language towards pointer arithmetic; for example, b[s] is equivalent to *(b+s), a subject I discuss in my written works. If not, both procedure implementations execute equally and produce comparable results.
I next want to alter the source code to ensure many characters are handled through the array once these applications have successfully run. The subsequent patch incorporates adjustments to the main () method but does not require modifications to the print () method.
The other example of this can be written as:
#include <stdio.h>
void output (char *b)
{
int s = 0;
while (*(b+s))
{
putchar(*(b+s));
s++;
}
putchar('\n');
}
int main ()
{
char *str [3] = {
"This is JTP",
"The acronym is Java T Point",
"This is very helpful to me."
};
int s;
For (s=0; s<3; s++){
output(str[s]);}
return (0);}
In this program, we pass the number of strings to the function by increasing the value of b to give strings of several lines to the function.

Explanation
Several variables are defined in this program's code around position seventeen. The declaration refers to an array of character suggestions, each pointing towards a text kept in storage. It's crucial to remember this detail since I've finally forgotten it.
Every character is passed through the output () development, which employs reference syntax, as was previously demonstrated, via a while loop. All three lines were output correctly, and everything is in working order. The true name of the data collection is **string, not *string []. The fact that an algorithm gets onto and alters letters in threads manifests this connection.
Conclusion
With links corresponding to textual figurative language, it is not feasible to alter the character array.eferences are identical, the value of *s within main () additionally equals 16.
A string of characters might be supplied to be input into the method as a reference, or it can be provided as an individual character collection.
You can modify texts using addresses because character arrays behave like points.
