How does a C program to find largest number using dynamic memory allocation work?

 Courtesy: Programiz.com


In the program, we have asked the user to enter the total number of elements which is stored in the variable n. Then, we have allocated memory for n number of double values.

// Allocating memory for n double values
data = (double *)calloc(n, sizeof(double));

Then, we used a for loop to take n number of data from the user.

// Storing elements
for (int i = 0; i < n; ++i) {
  printf("Enter Number%d: ", i + 1);
  scanf("%lf", data + i);
}

Finally, we used another for loop to compute the largest number.

// Computing the largest number
for (int i = 1; i < n; ++i) {
  if (*data < *(data + i))
    *data = *(data + i);
  }
}

Note: Instead of calloc(), it's also possible to solve this problem using the malloc() function.

Differentiate entry control and exit control loop.

  Difference between Entry control loop and Exit control loop: Basic Of Comparision Entry Controlled Loop Exit Controlled Loop Description Entry controlled loop is a loop in which the test condition is checked first, and then the loop body will be executed. Exit controlled loop is a loop in which the loop body is executed first and then the given condition is checked afterward. False Test Condition If the test condition is false, the loop body will not be executed. If the test condition is false, the loop body will be executed at least once. Example Examples of entry-controlled loops include, for loop and while loop. An example of an exit controlled loop is do…while Loop. Use Entry controlled loops are used when checking of test condition is mandatory before executing the loop body. Entry controlled loop is used when checking of test condition is mandatory after executing. Drafted on 🌏 by, Jal ☮ peace
