C Strings : C Programming Strings
Category: C LANGUAGE | 6th October 2023, Friday
In C Programming, Strings Are Sequences Of Characters Stored In An Array. In C, Strings Are Represented As Arrays Of Characters Terminated By A Null Character ('\0'), Which Indicates The End Of The String. Here Are Some Key Points About Working With Strings In C:
Declaring Strings:
Strings In C Can Be Declared As Character Arrays. For Example:
char Str[6] = "Hello"; // Declares A String With Size 6 (including The Null Character)
Initializing Strings:
Strings Can Be Initialized At The Time Of Declaration:
char Str[] = "Hello"; // Size Is Automatically Determined Based On The Length Of The String
Input And Output Of Strings:
You Can Use printf() And scanf() Functions For Input And Output Of Strings:
printf("Enter A String: ");
scanf("%s", Str); // Reads A String From The User
printf("You Entered: %s\n", Str); // Prints The String
String Functions:
C Provides Several Standard Library Functions For Working With Strings, Such As:
strlen(): Returns The Length Of A String.strcpy(): Copies One String To Another.strcat(): Concatenates Two Strings.strcmp(): Compares Two Strings.strchr(): Finds The First Occurrence Of A Character In A String.strstr(): Finds The First Occurrence Of A Substring In A String.
Example Of Using Some Of These Functions:
int main() {
char Str1[20] = "Hello";
char Str2[20] = " World";
// Concatenating Strings
strcat(str1, Str2);
printf("Concatenated String: %s\n", Str1);
// Length Of The String
printf("Length Of The String: %d\n", strlen(str1));
// Comparing Strings
if (strcmp(str1, "Hello World") == 0) {
printf("Strings Are Equal.\n");
} else {
printf("Strings Are Not Equal.\n");
}
return 0;
}
Remember That In C, Strings Are Arrays Of Characters, And You Need To Ensure That Your Arrays Are Large Enough To Store The Strings Along With The Null Terminator. Also, Be Cautious About Buffer Overflows, As C Does Not Perform Bounds Checking On Arrays.
