Question 1

Problem Statement – :

Check for syntax error/ logical error and correct the error to get the desired output.

The following code snippet finds out the last digit of a number entered by the user.

• For example– If the user enters a number 56, than the output will be 6

The code snippets accepts a single argument – num representing the number entered by the user.

The code snippet compiles successfully but fails to get the desired results for some test cases due to logical errors. Your task is to fix the code, so that it passess all the test cases

void palindrome(int number)
{
    int rev = 0,store, n1,left;
    n1=number;
    store= number;
    while (number > 0)
      {
        left= number%10;   //these are the correct lines
        rev = rev * 10 + left; //these are the correct lines
        number=number/10;  //these are the correct lines
       }
    if(n1==rev)
        printf("Number %d is Palindrome number",n1);
    else
        printf("it is not a Palindrome number");
}

#include<stdio.h>
int main()
{
char c;
int isLowerVowel, isUpperVowel;
printf("Enter an alphabet: ");
scanf("%c",&c);

isLowerVowel = (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u');

isUpperVowel = (c == 'A' || c == 'E' || c == 'I' || c == 'O' || c == 'U');

if (isLowerVowel && isUpperVowel)
printf("%c is a vowel", c);

else if((c >= 'a' || c== 'A')&& c <= 'Z')
printf("\n not a alphabet\n");

else
printf("%c is a consonant", c);

return 0;
