Q10. Find the output of the following C program a) 5, 4 b) 5, 5 c) 4, 4 d) 3, 4
Answer: c) 4, 4
Assignment
Question 1 Write a C Program to find Largest Element of an Integer Array. Here the number of elements in the array ‘n’ and the elements of the array is read from the test data. Use the printf statement given below to print the largest element. printf(“Largest element = %d”, largest);
Solution:
largest = arr[0];
for(i = 1; i < n; ++i)
{
if(largest < arr[i])
largest = arr[i];
}
printf("Largest element = %d", largest);
return 0;
}
Question 2 Write a C Program to print the array elements in reverse order (Not reverse sorted order. Just the last element will become first element, second last element will become second element and so on) Here the size of the array, ‘n’ and the array elements is accepted from the test case data. The last part i.e. printing the array is also written. You have to complete the program so that it prints in the reverse order.
Solution:
int j, temp;
j = i - 1; // last Element of the array
i = 0; // first element of the array
while(i < j)
{
temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
i++;
j--;
}
Question 3 Write a C program to read Two One Dimensional Arrays of same data type (integer type) and merge them into another One Dimensional Array of same type.
Solution:
for (i = 0; i < n2; i++)
scanf("%d", &arr2[i]);
int j;
for(i=0;i<n1;++i)
array_new[i]=arr1[i];
size = n1 + n2;
for(i=0, j=n1; j<size && i<n2; ++i, ++j)
array_new[j] = arr2[i];
Question 4 Write a C Program to delete duplicate elements from an array of integers.
Solution:
int j, k;
for(i = 0; i < size; i++) {
for(j = i + 1; j < size;) {
if(array[j] == array[i]) {
for (k = j; k < size; k++) {
array[k] = array[k + 1];
}
size--;
} else
j++;
}
}

Q3. The elements of array are stored in contiguous memory due to a) This way computers can keep track of only the address of the first element and the addresses of other elements can be calculated. b) The architecture of computer does not allow arrays to store other than serially c) Both (a) and (b) are true d) None of these are true
Answer: a) This way computers can keep track of only the address of the first element and the addresses of other elements can be calculated.
