If fx equals int x find the function value f71.19?
f(71.19) = 71 where int(x) is the integer value of a number
Develop program code for two by two matrix multiplication?
/* Multiplication of matrics is very easy in c, here is code below */#include main(){int temp=0;int arr[3][3]={1,2,3,4,5,6,7,8,9};int arr1[3][3]={10,11,12,13,14,15,16,17,18} ;for(int i=0;i
30 examples of variables?
int n1; int n2; int n3; int n4; int n5; int n6; int n7; int n8; int n9; int n10; int n11; int n12; int n13; int n14; int n15; int n16; int n17; int n18; int n19; int n20; int n21; int n22; int n23; int n24; int n25; int n26; int n27; int n28; int n29; int n30;
Deifference between declaration and definition?
Declaring a variable or function reserves an entry in a symbol table for that function or variable (entries in a symbol table eventually become memory addresses during linkage). Defining a variable or function actually specifies the value to be stored in the memory location specified and/or the code that should be compiled. Examples: Declaration: int foo(); // Declares a function. int bar; // Declares a variable. Definition: int foo() { printf("Hello World"); } bar = 5; Declaration and definition: int bar = 5;
Java source code to find prime number?
/* Program to Find whether number is Prime or Not. */ class PrimeNo{ public static void main(String args[]){ int num = Integer.parseInt(br.readLine()); int flag=0; for(int i=2;i
What is difference between volatile int and const volatile int?
volatile int means the code and fom outside from code can changes the value but in const volatile int, code cannot changes the value but fron ouside can change the value
Source code for LinearSearch in java?
// Returns the index of n in ns or -1 if not found. public static final int linearSearch(final int n, final int[] ns) { for(int i = 0; i < ns.length; ++i) { // If found, return the index if(ns[i] == n) { return i; } } return -1; }
Must all final variables be compile time constants?
No, it is not mandatory. As long as a final variable is initialized only once during the sequence of the code flow, the compiler would not complain. Ex: public class Test { final int x; public void assignVal(int val){ if(val > 100) { x = val; } } } The above code will compile and run just fine as long as there is no other line in the code that assigns a value for x.
Design iterative and recursive alogrithm to find the minimum among n elements?
// returns the minimum value in ns - iterative public static final int findMinIterative(final int[] ns) { if (ns.length == 0) { return 0; // return 0 if ns is an empty array } // search each element of ns int min = ns[0]; for (int i = 0; i < ns.length; ++i) { // if an element smaller than min is found, store that as the new min if (ns[i] < min) { min = ns[i]; } } return min; } // returns the minimum value in ns - recursive // Note that this problem does not lend itself to recursion; the solution is very similar to the iterative approach public static final int findMinRecursive(final int[] ns) { if (ns.length == 0) { return 0; // return 0 if ns is an empty array } // start recursion return findMinRecursive(0, ns[0], ns); } // recursive part of algorithm private static final int findMinRecursive(final int i, final int min, final int[] ns) { // bounds check if (i >= ns.length) { return min; } // recurse on next value of ns return findMinRecursive(i + 1, Math.min(min, ns[i]), ns); }
What if you feed an int value and an unsigned int value?
Feed? What do you mean by that
What is the purpose of call by value in java?
Simple types are passed by value in Java. For example: void meth(int a) { // code } meth(34); // 34 is passed by value
What value is return by int main method?
1. A method declared as "int" returns an int value. 2. The main() method in Java is not declared as "int", but as "void", meaning it returns no value.
What is the C plus plus code to print all ASCII codes and the equivalent characters?
Although character data types such as char are intrinsically numeric, whenever you print a char you automatically print the symbol associated with the character code (the char's value), never the code. In order to print the code you must cast the character to a numeric data type, such as int. char c = 'A'; // ASCII value 65 decimal (0x41) std::cout << static_cast<int>(c); // puts the value 65 on std::cout
Given 2 int arrays a and b each length 3 return a new array length 2 containing their middle elements?
Java solutionpublic static final int[] getMiddle(final int[] a, final int[] b) {return new int[] {a[1], b[1]};}C solution void getMiddle(const int a[], const int b[], int ret[]) {ret[0] = a[1];ret[1] = b[1];}
What is the difference between declaration and initialization?
Perhaps an example will help. extern int value; /* declaration */ int value; /* definition */ int value= 20; /* definition with initialization */
Write a program to calculate the sum of the sequence number from 1 to n loop?
public static final int getSum(final int n) { int sum = 0; for(int i = 1; i <= n; ++i) { sum += i; } return sum; }
What are the qualifiers that an int can have at a time?
A signed int can take a value between -32768 to 32767 and an unsigned int can take a value 0 to 65535.
