how to make string using c code example

Example 1: string in c

#include 

int main(void) {
  char name[] = "Harry Potter";

  printf("%c", *name);     // Output: H
  printf("%c", *(name+1));   // Output: a
  printf("%c", *(name+7));   // Output: o

  char *namePtr;

  namePtr = name;
  printf("%c", *namePtr);     // Output: H
  printf("%c", *(namePtr+1));   // Output: a
  printf("%c", *(namePtr+7));   // Output: o
}

Example 2: string in c

#include 

int main() {
  char *str1 = strdup("Hello");
  char *str2 = malloc(sizeof(char) * (strlen(str1) + 1));
  
  for (int i = 0; i < strlen(str1); ++i)
    str2[i] = str1[i];
  str2[strlen(str1)] = '\0'; // very important, the string stop to print
  printf("%s --> %s\n", str1, str2);
}
