Q.1.
write c ++ program to perform given operations two
input integers.
CODE :
#include <iostream>
int main() {
int a = 2;
int b = 4;
std::cout << "Addition: " << a + b << std::endl;
std::cout << "Subtraction: " << a - b << std::endl;
std::cout << "Multiplication: " << a * b << std::endl;
std::cout << "Division: " << a / b << std::endl;
std::cout << "Modulus: " << a % b << std::endl;
std::cout << "Increment a: " << ++a << std::endl;
std::cout << "Decrement b: " << --b << std::endl;
return 0;
}
Q.2. Write a C++ code for calculating the Average and The
Percentage of the Students marks.
CODE:
#include <iostream>
int main() {
int marks[5] = {85, 90, 78, 88, 92};
int total = 0;
float average, percentage;
for (int i = 0; i < 5; ++i) {
total += marks[i];
}
average = total / 5.0;
percentage = (total / 500.0) * 100;
std::cout << "Total Marks: " << total << std::endl;
std::cout << "Average Marks: " << average << std::endl;
std::cout << "Percentage: " << percentage << "%" <<
std::endl;
return 0;
}
Q.3. Write C++ program to swap two numbers.
CODE:
#include <iostream>
int main() {
int a = 5;
int b = 10;
int temp;
temp = a;
a = b;
b = temp;
std::cout << "After swapping, a = " << a << " and b = " << b <<
std::endl;
return 0;
}
Q.4 Write C++ program to display array of 10 numbers.
CODE:
#include <iostream>
int main() {
int numbers[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
std::cout << "Array elements are: ";
for (int i = 0; i < 10; ++i) {
std::cout << numbers[i] << "\n";
}
std::cout << std::endl;
return 0;
}
Q.5 Write cpp program to perform addition of 2 matrices
CODE:
#include <iostream>
int main() {
int matrix1[3][3] = { {1, 2, 3},{4, 5, 6}, {7, 8, 9} };
int matrix2[3][3] = { {9, 8, 7}, {6, 5, 4}, {3, 2, 1} };
int sum[3][3];
for (int i = 0; i < 3; ++i) {
for (int j = 0; j < 3; ++j) {
sum[i][j] = matrix1[i][j] + matrix2[i][j];
}
}
std::cout << "Sum of the matrices:" << std::endl;
for (int i = 0; i < 3; ++i) {
for (int j = 0; j < 3; ++j) {
std::cout << sum[i][j] << " ";
}
std::cout << std::endl;
}
return 0;
}
