Question 3 Write a C program to store n elements using Dynamic Memory Allocation – calloc() and find the Largest element
Solution:
element = (float*) calloc(n, sizeof(float));
if(element == NULL)
{
printf("Error!!! memory not allocated.");
exit(0);
}
int ide;
for(ide = 0; ide < n; ++ide)
{
scanf("%f", element + ide);
}
for(ide = 1; ide < n; ++ide)
{
if(*element < *(element + ide))
*element = *(element + ide);
}
printf("Largest element = %.2f\n", *element);
return 0;
}
Question 4 Write a C program to find the sum of two 1D integer arrays ‘A’ and ‘B’ of same size and store the result in another array ‘C’, where the size of the array and the elements of the array are taken as input. In the Test case the input is given as follows 5 10 20 30 40 50 1 2 3 4 5 So the output will be displayed as Result is 11 22 33 44 55
