Answer:
Explanation: As director of the Electronic Computer Project at Princeton's Institute for Advanced Study (1945-1955), he developed MANIAC (mathematical analyzer, numerical integrator, and computer), which was at the time the fastest computer he was also one of the conceptual inventors of the stored-program digital computer.
John von Neumann's significant contribution to computer development was his invention of the von Neumann architecture, enabling programmable computers.
John von Neumann, the virtuoso polymath hailing from Hungary, emerged as a brilliant luminary who graced the 20th century with his unparalleled contributions to mathematics, physics, and computer science.
Proficient in quantum mechanics, game theory, and nuclear physics, he navigated an intellectual universe as vast as the cosmos itself. Yet, it was the von Neumann architecture, the monument of his ingenuity, that etched his name indelibly in the history of computing.
Like a maestro conducting an orchestra of ideas, von Neumann orchestrated a symphony of innovation, transforming the world with his multifaceted genius and forever inspiring the pursuit of knowledge.

If a program contains an error that divides a number by zero at the execution time. this error is a:_________
If a program contains an error that divides a number by zero at the execution time. this error is a Semantic error.
Text that is grammatically correct but makes no sense is a semantic mistake. In the case of the C# programming language, an illustration would be "int x = 12.3;" - This sentence is illogical since 12.3 is not an integer literal and there is no implicit conversion from 12.3 to int. However, it is grammatically sound.
The disruption of access to semantics or lexical representations leads to semantic mistakes. Examining the understanding of words that cause name semantic problems is one technique to identify their causes.
A semantic error is flawed logic that results in the incorrect behaviour when applied, as opposed to a syntax error, which is an incorrect construction of the source code.

Write an if statement involving a boolean operator (and, or or not) which performs the same function as the following nested if statement: if day == "sunny" if temperature > 20 picnic = "yes" else picnic = "no" endif endif
The given question requires that we need to rewrite the if-else statement using boolean operators such as “and”, “or”, and “or not”
The if-else statement is used to evaluate the condition and execute some instruction or perform some task in case the condition is true, otherwise, execute the else part of the if-else statement.
In the if-else conditions, you can evaluate the expression using boolean operators such as and, or, on not, etc.
The given statement can be rewritten in any programming language. But here we use C++ to rewrite the given statement involving boolean operators:
Use of “and” operator:
#include <iostream>
using namespace std;
int main()
{
string day = "sunny";
int temperature =10;
string picnic = "Yes";
if (day =="sunny" && temperature ==10)
{
picnic = "Yes";
std::cout<<picnic;}
else
{
picnic="No";
std::cout<<picnic;}
return 0;
}
Use of “or” operator:
#include <iostream>
using namespace std;
int main()
{
string day = "sunny";
int temperature =10;
string picnic = "Yes";
if (day =="sunny" || temperature ==10)
