Write a program in c which will read a string rewrite it in alphabetical order?

Answer 1

#include<stdio.h>

#include<string.h>

#include<conio.h>

void main()

{

char a[30],temp;

int n=0,j,i;

clrscr();

printf("Enter the string\n");

gets(a);

while(a[n]!='\0')

{

n++;

}

for(i=0;i<n;i++)

{

for(j=0;j<n-i-1;j++)

{

if(a[j]>a[j+1])

{

temp=a[j];

a[j]=a[j+1];

a[j+1]=temp;

}

}

}

printf("The string in alphabetical order is\n");

for(i=0;i<n;i++)

{

printf("%c",a[i]);

}

getch();

}

Answer 2

Here is a simple C program that reads a string from the user, then sorts the characters of the string in alphabetical order:

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

int main() {
    char str[100];
    printf("Enter a string: ");
    fgets(str, sizeof(str), stdin);
    
    int len = strlen(str);
    for (int i = 0; i < len; i++) {
        for (int j = i+1; j < len; j++) {
            if (str[i] > str[j]) {
                char temp = str[i];
                str[i] = str[j];
                str[j] = temp;
            }
        }
    }
    
    printf("The string in alphabetical order is: %s\n", str);
    
    return 0;
}
