C programs | Swapping of two numbers without third(temp) variable in C

Source Code:-)

#include <stdio.h>

int main()
{
   int a, b;

   printf("Enter two integers to swap\n");
   scanf("%d%d", &a, &b);

   a = a + b;
   b = a - b;
   a = a - b;

   printf("a = %d\nb = %d\n",a,b);
   return 0;

C programs | Swapping of two numbers in c

Source code:-)

#include <stdio.h>

int main()
{
   int x, y, temp;

   printf("Enter the value of x and y\n");
   scanf("%d%d", &x, &y);

   printf("Before Swapping\nx = %d\ny = %d\n",x,y);

   temp = x;
   x    = y;
   y    = temp;

   printf("After Swapping\nx = %d\ny = %d\n",x,y);

   return 0;
}

Output:-)

Enter the value of x and y

3

6

Before swapping 

x=3 

y=6 

After swapping

x=6

y=3

C Program | To Find ASCII Value of a Character

Source code:-)

 /* Source code to find ASCII value of a character entered by user */

#include <stdio.h>
int main(){
    char c;
    printf("Enter a character: ");
    scanf("%c",&c);        /* Takes a character from user */
    printf("ASCII value of %c = %d",c,c);
    return 0;
}

Output:-)

Enter a character: G
ASCII value of G = 71

C Program-Find Size of int, float, double and char of System-Syntax-Source Code-Output

 C Program-Find Size of int, float, double and char of System

Syntax of size of Operator:-

 temp = sizeof(operand);
/* Here, temp is a variable of type integer,i.e, sizeof() operator
   returns integer value. */

 

Source Code :-)

/* This program computes the size of variable using sizeof operator.*/ 

#include <stdio.h> 

int main()

{ 

int a; 

float b; 

double c; 

char d; 

printf("Size of int: %d bytes\n",sizeof(a)); 

printf("Size of float: %d bytes\n",sizeof(b)); 

printf("Size of double: %d bytes\n",sizeof(c)); 

printf("Size of char: %d byte\n",sizeof(d)); 

return 0; 

}

OUTPUT :-)

Size of int: 4 bytes
Size of float: 4 bytes
Size of double: 8 bytes
Size of char: 1 byte
