Program Listing

#include <stdio.h>

#include <conio.h>

void main( )

{

int a[5] = { 11, 2, 9, 13, 57 } ;

int b[5] = { 25, 17, 1, 90, 3 } ;

int c[10] ;

int i, j, k, temp ;

printf ( "Merge sort.\n" ) ;

printf ( "\nFirst array:\n" ) ;

for ( i = 0 ; i <= 4 ; i++ )

printf ( "%d\t", a[i] ) ;

printf ( "\n\nSecond array:\n" ) ;

for ( i = 0 ; i <= 4 ; i++ )

printf ( "%d\t", b[i] ) ;

for ( i = 0 ; i <= 3 ; i++ )

{

for ( j = i + 1 ; j <= 4 ; j++ )

{

if ( a[i] > a[j] )

{

temp = a[i] ;

a[i] = a[j] ;

a[j] = temp ;

}

if ( b[i] > b[j] )

{

temp = b[i] ;

b[i] = b[j] ;

b[j] = temp ;

}

}

}

for ( i = j = k = 0 ; i <= 9 ; )

{

if ( a[j] <=  b[k] )

c[i++] = a[j++] ;

else

c[i++] = b[k++] ;

if ( j == 5 || k == 5 )

break ;

}

for ( ; j <= 4 ; )

c[i++] = a[j++] ;

for ( ; k <= 4 ; )

c[i++] = b[k++] ;

printf ( "\n\nArray after sorting:\n") ;

for ( i = 0 ; i <= 9 ; i++ )

printf ( "%d\t", c[i] ) ;
