C in Arrays programs

4. Program

#include 

#include 

int max(int num1, int num2);

int main ()

{

   int a = 100;

   int b = 200;

   int ret;

     ret = max(a, b);

   printf( "Max value is : %d\n", ret );

   return 0;

}

int max(int num1, int num2) 

{

      int result;

   if (num1 > num2)

      result = num1;

   else

      result = num2;

   return result; 

   getch();

}

Output

               Max value is : 200

5. Program

#include 

#include 

void main ()

{

  int a = 10;

  int b = 20;

  int c = 0;

  clrscr();

  printf ("value of a in main() = %d\n",  a);

  c = sum( a, b);

  printf ("value of c in main() = %d\n",  c);

              return 0;

}

int sum(int a, int b)

{

    printf ("value of a in sum() = %d\n",  a);

    printf ("value of b in sum() = %d\n",  b);

    return a + b;

    getch();

}

Output

value of a in main() = 10

value of a in sum() = 10

value of b in sum() = 20

value of c in main() = 30

6. Program

#include 

#include 

int main ()

{

   int n[ 10 ]; 

   int i,j;

      for ( i = 0; i < 10; i++ )

   {

      n[ i ] = i + 100;

   }

   for (j = 0; j < 10; j++ )

   {

      printf("Element[%d] = %d\n", j, n[j] );

   }

   return 0;

   getch();

}

Output

Element[0] = 100

Element[1] = 101

Element[2] = 102

Element[3] = 103

Element[4] = 104

Element[5] = 105

Element[6] = 106

Element[7] = 107

Element[8] = 108

Element[9] = 109

7. Program

          #include 

#include 

int main ()

{

   int  var1;

   char var2[10];

   printf("Address of var1 variable: %x\n", &var1  );

   printf("Address of var2 variable: %x\n", &var2  );

   return 0;

   getch();

}

Output

Address of var1 variable: bff5a400

Address of var2 variable: bff5a3f6
