Q.77 Write c program which display mouse pointer and position of pointer.(In x coordinate, y coordinate)?

#include”dos.h” #include”stdio.h” void main() { union REGS i,o; int x,y,k; //show mouse pointer i.x.ax=1; int86(0x33,&i,&o); while(!kbhit()) //its value will false when we hit key in the key board { i.x.ax=3; //get mouse position x=o.x.cx; y=o.x.dx; clrscr(); printf("( d , d)",x,y); delay(250); int86(0x33,&i,&o); } getch(); }

#include<stdio.h> int main() { int intType; float floatType; double doubleType; char charType; // sizeof evaluates the size of a variable printf("Size of int: %zu bytes\n", sizeof(intType)); printf("Size of float: %zu bytes\n", sizeof(floatType)); printf("Size of double: %zu bytes\n", sizeof(doubleType)); printf("Size of char: %zu byte\n", sizeof(charType)); return 0; }

#include<stdio.h> int main() { double first, second, temp; printf("Enter first number: "); scanf("%lf", &first); printf("Enter second number: "); scanf("%lf", &second); // Value of first is assigned to temp temp = first; // Value of second is assigned to first first = second; // Value of temp (initial value of first) is assigned to second second = temp; printf("\nAfter swapping, firstNumber = %.2lf\n", first); printf("After swapping, secondNumber = %.2lf", second); return 0; }
