Pictorial Presentation:

Display Pascal's triangle

Sample Solution:

C Code:

#include <stdio.h>

void main()
    int no_row,c=1,blk,i,j;
    printf("Input number of rows: ");
        printf("  ");
            if (j==0||i==0)
            printf("% 4d",c);

Sample Output:

Input number of rows: 5                                                                                       
           1   1                                                                                              
         1   2   1                                                                                            
       1   3   3   1                                                                                          
     1   4   6   4   1

C Programming: Tips of the Day

Clearing a char array c

It depends on how you want to view the array. If you are viewing the array as a series of chars, then the only way to clear out the data is to touch every entry. memset is probably the most effective way to achieve this.

On the other hand, if you are choosing to view this as a C/C++ null terminated string, setting the first byte to 0 will effectively clear the string.
