Exercise 3.29 & 3.30 (Deitel: C How to Program 6th Edition)

3.29 What does the following program print?

 #include <stdio.h>

 int main( void ) {
 int count = 1; /* initialize count */

 while ( count <= 10 ) { /* loop 10 times */
 /* output line of text */
 printf( "%s\n", count % 2 ? "****" : "++++++++" );
 count++; /* increment count */
 } /* end while */
 system("pause");
 return 0; /* indicate program ended successfully */
 } /* end function main */

Output:

3.30 What does the following program print?

 #include <stdio.h>

 int main( void )
 {
 int row = 10; /* initialize row */
 int column; /* define column */

 while ( row >= 1 ) { /* loop until row < 1 */
 column = 1; /* set column to 1 as iteration begins */

 while ( column <= 10 ) { /* loop 10 times */
 printf( "%s", row % 2 ? "<": ">" ); /* output */
 column++; /* increment column */
 } /* end inner while */
 row--; /* decrement row */
 printf( "\n" ); /* begin new output line */ } /* end outer while */
 system("pause");
 return 0; /* indicate program ended successfully */
 } /* end function main */

Output:
