Problem Set A
1
.
For each of the following programming languages: investigate the language. Is the language low-level, middle-level, or high-level? Which of the paradigms covered in this section apply to the language (imperative, declarative, functional, structured, procedural, object-oriented)? Cite your sources.
- Kotlin
- Lisp
- PASCAL
2
.
Explain how levels of abstraction affect speed of development and speed of execution.
3
.
Explain how a compiler assists in providing abstractions for high-level languages.
4
.
Write a module titled “triangle operations” that has two functions: one to compute the area of a triangle given a base and height and one to compute the perimeter of the triangle given three sides. Then, write a main function that iterates three times, increasing each variable by one, and then calls each function.

OpenMP provides the
omp_get_thread_num() function in the header file omp.h. To get the number of total running threads in the parallel block, you can use function omp_get_num_threads. How can you modify this program to ensure that only one thread executes the “Greetings from process” printf statement?
#include <stdio.h>
#include <omp.h>
int main() {
#pragma omp parallel num_threads(3)
{
int id = omp_get_thread_num();
int data = id;
int total = omp_get_num_threads();
printf("Greetings from process %d out of %d with Data %d\n", id, total, data);
}
printf("parallel for ends.\n");
return 0;
}
