C string

#include <stdio.h>
#include <stdlib.h>
#include <string.h> // string.h adds a lot of pre-defined functions

int main() {
  // There are 2 ways to define a basic string in C:
  char string1[] = "This is a string!";
  // Notice that here, I use the brackets [] to tell C that this is a
  // char array. 
  
  // I can also define a string this way:
  char* string2 = "This is another string!";
  
  // If I didn't want to ititialize the string yet:
  char string3[10];
  // This creates a string 10 bytes long, with no value initialized yet.
  // Another way to do this is by using malloc/calloc:
  char* string4 = malloc(10);
  // However, with this method, I would have to free the string later,
  // because it is stored on the heap:
  
  free(string4);
}

strings in c

#include <stdlib.h>
#include <string.h>
#include <stdio.h>

#define MAX_LENGTH 100
#define NUM_STRINGS 10

int main(){

    char arr[NUM_STRINGS][MAX_LENGTH] = {""};

    arr2[0] = "string literal"; // Not permitted
    strcpy(arr[0], "hello world");
    printf("%s
", arr[0]);
    printf("%s
", strcpy(arr[0], "hello world"));

    exit(EXIT_SUCCESS);

c language string

//BY SAMEERAZ
#include<stdio.h>
#include<conio.h>
void main(){
char string[50];
clrscr();
printf("ENTER STRING:");
gets(s);//gets is basically used as scanf();
printf("TYPED STRING:%s",string);
getch();
}

declare string in c

char string[20];

string in c

1. char str[] = "GeeksforGeeks";

2. char str[50] = "GeeksforGeeks";

3. char str[] = {'G','e','e','k','s','f','o','r','G','e','e','k','s',''};

4. char str[14] = {'G','e','e','k','s','f','o','r','G','e','e','k','s',''};

what are strings in c

// C program to illustrate strings
  
#include <stdio.h>
#include <string.h>
  
int main()
{
    // declare and initialize string
    char str[] = "Geeks";
  
    // print string
    printf("%s
", str);
    
    int length = 0;
    length = strlen(str);
    
      // displaying the length of string
    printf("Length of string str is %d", length);
  
    return 0;
}

string in c and how it works

Strings are defined as an array of characters. The difference between a 
character array and a string is the string is terminated with a special
character ‘’.
