ক্যারেক্টার টাইপের অ্যারে এবং স্ট্রিং – সি কোড

ক্যারেক্টার টাইপের এক-মাত্রিক অ্যারে হল স্ট্রিং যা নাল (‘\ 0’) দ্বারা সমাপ্ত ।

অর্থাৎ নাল (‘\ 0’) পেলেই মনে করে স্টিং শেষ।

অ্যারের প্রতিটি অক্ষর মেমরির একটি বাইট দখল করে এবং সর্বশেষ অক্ষরটি সমাপ্তি অক্ষর (‘\ 0’).

#include<stdio.h>
int main()
{
    char name;
    printf("Enter name = ");
    scanf("%c", &amp;name);
    printf("You Entered name = %c", name);

    return 0;
}

Output

Enter name = bncodeing
You Entered name = b

এখানে, শুধু রকটি ক্যারেক্টার নিতে পারছে। চল দেখি কিভাবে একটি ওয়ার্ড, লাইন নিতে পারি।

দুই প্রকার অ্যারে আছে

  • ক্যারেক্টার টাইপের অ্যারে
  • স্টিং লিটারাল
#include<stdio.h>
int main()
{
    char name;
    char ch[]={'b', 'n', 'c', 'o', 'd', 'e', 'i', 'n', 'g','\0'};
    printf("%s", ch);

    return 0;
}

আউটপুট 

bncodeing

এখানে, যে ভাবে আমি ডিক্লিয়ার করেছি এটি একটি অ্যারে যার ০ পজিশনে ‘b’, ১ পজিশনে ‘n’, ৩ পজিশনে ‘c’ …………৯ পজিশনে ‘\0’

অ্যারের সাইজ না দিয়েই ডিক্লিয়ার করেছি ইচ্ছা করলে তুমরা সাইজ দিতে পার।

#include<stdio.h>
#include <string.h>
int main(){
    char ch[11]={'b', 'n', 'c', 'o', 'd', 'e', 'i', 'n', 'g','\0'};
    char ch2[11]="bncodeing";

    printf("Char Array Value is: %s\n", ch);
    printf("String Literal Value is: %s\n", ch2);
    
    return 0;
}

Output

Char Array Value is: bncodeing
String Literal Value is: bncodeing

চল আমরা একটি শব্দ হতে ভাউয়েল কয়টি কাউন্ট করি 

#include<stdio.h>
void main ()
{
    char s[10] = "bncodeing";
    int i = 0;
    int count = 0;
    while(s[i] != NULL)
    {
        if(s[i]=='a' || s[i] == 'e' || s[i] == 'i' || s[i] == 'u' || s[i] == 'o')
        {
            count ++;
        }
        i++;
    }
    printf("The number of vowels %d",count);
}

Output

The number of vowels 3

স্টিং লিটারাল এতে আমরা যে ভাবে স্টিং ইনপুট নিব 

#include<stdio.h>
void main ()
{
    char s[20];
    printf("Enter the string = ");
    scanf("%s",s);
    printf("You entered= %s",s);
}

Enter the string = bncodeing is best
You entered= bncodeing

%s দিয়ে ইনপুট নিলে স্পেস পেলে নাল ধরে নেয়ে শেষ করে দেয়। চল দেখি কিভাবে একটি লাইন ইনপুট নিতে পারি

#include<stdio.h>
void main ()
{
    char s[20];
    printf("Enter the string =");
    scanf("%[^\n]s",s);
    printf("You entered =  %s",s);
}

Enter the string =bncodeing is best
You entered =  bncodeing is best

কাজ

  • ভাউয়েল কিনা যাচাই এর কোড লিখ
  • তুমার নাম লিখ ইনপুট নিয়ে

    discovered any attention-grabbing article like yours.

    It is beautiful value enough for me. In my opinion, if all site owners and
    bloggers made good content material as you did, the internet shall be
    much more useful than ever before.

    Today, I went to the beach with my kids. I found a sea shell and gave it
    to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the
    shell to her ear and screamed. There was a hermit crab inside and it pinched her ear.
    She never wants to go back! LoL I know this is totally off topic but I had to tell someone!
