Passing Strings to Functions
String can be passed to function in similar manner as arrays as, string is also an array. Learn more about passing array to a function.
#include <stdio.h>
void Display(char ch[]);
int main(){
char c[50];
printf("Enter string: ");
gets(c);
Display(c); // Passing string c to function.
return 0;
}
void Display(char ch[]){
printf("String Output: ");
puts(ch);
}
Here, string c is passed from main() function to user-defined function Display(). In function declaration, ch[] is the formal argument.
String handling functions
You can perform different type of string operations manually like: finding length of string, concatenating(joining) two strings etc. But, for programmers ease, many library function are defined under header file <string.h> to handle these commonly used talk in C
programming. You will learn more about string hadling function in next chapter.
String Manipulations In C Programming Using Library
Functions
Strings are often needed to be manipulated by programmer according to the need of a problem. All string manipulation can be done manually by the programmer but, this makes programming complex and large. To solve this, the C supports a large number of string handling functions.
There are numerous functions defined in "string.h" header file. Few commonly used string handling functions are discussed below: Function
