Write a program that reads two strings CH1 and CH2 and copies the first half of CH1 and the first half of CH2 into a third CH3. Show the result.

Use only the gets and puts functions.

#include <stdio.h>
void main()
{
	/* Declarations */
	char CH1[100], CH2[100]; /* given strings  */
	char CH3[100]="";        /* resulting string  */
	int L1,L2; /* length of CH1 and CH2        */
	int I;     /* counter for CH1 and CH2 */
	int J;     /* counter for CH3        */

	/* Reading */
	puts("Enter the first string : ");
	gets(CH1);
	puts("Enter the second string : ");
	gets(CH2);
 
	/* Determine the lengths of CH1 and CH2 */
	for (L1=0; CH1[L1]; L1++) ;
	for (L2=0; CH2[L2]; L2++) ;

	/* Copy the first half of CH1 to CH3 */
	for (I=0 ; I<(L1/2) ; I++)
		CH3[I]=CH1[I];
	/* Copy the first half of CH2 to CH3 */
	J=I;
	for (I=0 ; I<(L2/2) ; I++)
	{
		CH3[J]=CH2[I];
		J++;
	}
	/* Terminate the string CH3 */
	CH3[J]='\0';
 
	/* Display */
	puts("Resulting string : ");
	puts(CH3);
}
