End of Lecture 4arrow_forwardvoid main (void) { char result = a; for (char i = { 10; i > 5; i = i-1) result = result + i; } // point B } Consider the code above. What is the decimal value of "result" at "point B" if the variable "a" is initially 59?arrow_forwardCorrect and detailed answer will be Upvoted else downvoted Write a C++ Program To Create Empty Classarrow_forward
- User Defined Function: Void Function Create a JAVA program that will add, subtract, multiply and divide two numbers. Use user defined function for each operator Any number divided by zero will result to undefined Use int or double data type only for all variables declaredEXPECTED OUTPUT:arrow_forward// Return remainder after integer division // Global variables int a = 4; int b = 30; int main() { // Use registers for local variables int remainder; int divisor; } if (a > b) { } else { } remainder = a; divisor = b; } remainder = b; divisor = a; while (remainder > divisor) { remainder -= divisor; return remainder;arrow_forward#include #include void main(void) {int number; Cout > number; if ( number > 100) cout <<" number is greater then 100" ; else cout <" number is not greater than 100" ;arrow_forward
