Learn Programming

This blog is about providing theory as well as simple executable codes of different programming languages such as java, C, C++, and web programming, etc. This blog will be helpful to the IT students to learn about programming.

Write a program using the algorithm count() to count how many elements in a container have a specified value.

March 23, 2023 0
 Here's an example program using the count() algorithm to count the number of occurrences of a specific value in a vector container:#include <iostream>#include <vector>#include <algorithm>using namespace std;int main() {    vector<int> numbers = { 2, 5, 3, 7, 8, 5, 1, 5, 4 };        // count the number of occurrences of the value 5 in the vector    int count = count(numbers.begin(),...

Write a program in C++ using the find() algorithm to locate the position of a specified value in a sequence container.

  here's an example program using the find() algorithm to locate the position of a specified value in a vector:#include <iostream>#include <vector>#include <algorithm>using namespace std;int main() {    // Create a vector of integers    vector<int> vec = { 5, 2, 7, 9, 1, 8 };    // Find the position of the value 7 in the vector    auto it = find(vec.begin(), vec.end(), 7);    //...

Write a main program that calls a deeply nested function containing an exception. Incorporate necessary exception handling mechanism.

 Here's an example program that demonstrates a deeply nested function containing an exception, and incorporates exception handling:#include <iostream>using namespace std;void functionC(){    // A divide-by-zero exception will be thrown here    int x = 10, y = 0, z = x/y;}void functionB(){    functionC();}void functionA(){    functionB();}int main(){    try    {       ...

Write a program to demonstrate the concept of rethrowing an exception.

March 17, 2023 0
 In C++, an exception can be rethrown to be caught by another catch block. This allows for more fine-grained handling of exceptions in a program.Here is an example program that demonstrates rethrowing an exception:#include <iostream>using namespace std;void divide(int a, int b) {    try {        if (b == 0) {            throw "Division by zero error";        } ...

Write a program that demonstrates how certain exception types are not allowed to be thrown.

March 17, 2023 0
 In C++, there are certain types of exceptions that are not allowed to be thrown. These include void, function type, reference type, and array of non-zero bound with elements of these types.Let's see an example program that demonstrates this:#include <iostream>using namespace std;int main() {   try {      // Attempt to throw an exception of type void      throw void();   }   catch (...)...

Write a program that illustrates the application of multiple catch statements.

March 17, 2023 0
 Here's an example program that uses multiple catch statements to handle different types of exceptions:#include <iostream>#include <string>using namespace std;int main() {    try {        int num1, num2, result;        cout << "Enter two numbers to divide: ";        cin >> num1 >> num2;        if (num2 == 0) {       ...

Write a program containing a possible exception. Use a try block to throw it and a catch block to handle it properly.

March 17, 2023 0
 Here is an example program that demonstrates the use of try and catch block to handle an exception:#include <iostream>#include <string>using namespace std;void divide(int a, int b) {    if (b == 0) {        throw "Divide by zero exception";    }    cout << "a/b = " << a/b << endl;}int main() {    int a, b;    cout << "Enter two numbers: "; ...
