Answer:

Option B (grade1 + grade2 + grade3) / 3.0

Explanation:

The most accurate result is calculated by the expression given in the option B.  This is because all the <em>grade1</em>, <em>grade2</em> and <em>grade3</em> variables are integer type and therefore we need to add a decimal point after divisor (e.g. 3.0) so that the decimal points of the result can be preserved.

For example:

(88 + 92 + 83) / 3.0  should result in 87.66666666666667

If we do  (88 + 92 + 83) / 3, the decimal points are truncated to 87.

The expression in option c, (double)((grade1 + grade2 + grade3) / 3), will result in 87 as the  (grade1 + grade2 + grade3) / 3 will be evaluated first prior to converting into double type.

The expression in option d and e are inaccurate as they don't calculate average of the three variables.

A; you have to add the grades to have the total and then divide by 3 because there are 3 variables.

       int decimalExample = Integer.parseInt("20");  

       int signedPositiveExample = Integer.parseInt("+20");  

       int signedNegativeExample = Integer.parseInt("-20");  

       int radixExample = Integer.parseInt("20",16);  

       int stringExample = Integer.parseInt("geeks",29);  

 

       // Uncomment the following code to check

       //   String invalidArguments = "";  

       //   int emptyString = Integer.parseInt(invalidArguments);  

       //   int outOfRangeOfInteger = Integer.parseInt("geeksforgeeks",29);  

       //   int domainOfNumberSystem = Integer.parseInt("geeks",28);  

 

       System.out.println(decimalExample);  

       System.out.println(signedPositiveExample);  

       System.out.println(signedNegativeExample);  

       System.out.println(radixExample);  

       System.out.println(stringExample);  

   }  

}

Developed the first compiler and conducted work that led to the development of COBOL ?
zimovet [89]

Answer:

Grace Hopper.

Explanation:

Grace Hopper was a US Naval Rear Admiral and an American computer scientist who was born on the 9th of December, 1906 in New York city, United States of America. She worked on the first commercial computer known as universal automatic computer (UNIVAC), after the second World War II.

In 1953 at the Remington Rand, Grace Hopper invented the first high-level programming language for UNIVAC 1 by using words and expressions.

Additionally, the high-level programming language known as FLOW-MATIC that she invented in 1953 paved the way for the development of common business-oriented language (COBOL).

Hence, Grace Hopper developed the first compiler and conducted work that led to the development of COBOL.
