All totals should be stored in the double-subscripted array sales. After processing all the information for last month, print the results in tabular format with each of the columns representing a particular salesperson and each of the rows representing a particular product. Cross total each row to get the total sales of each product for last month; cross total each column to get the total sales by salesperson for last month. Your tabular printout should include these cross totals to the right of the totaled rows and to the bottom of the totaled columns. 3. (30 Marks) Write a program that inputs a line of text and a search string from the keyboard. Using function strstr, locate the first occurrence of the searclh string in the line of text, and assign the location to variable searchPtr of type 8 char *. If the search string is found, print the remainder of the line of text beginning with the search string. Then, use strstr again to locate the next occurrence of the search string in the line of text. If a second occurrence is found, print the remainder of the line of text beginning with the second occurrence. [Hint: The second call to strstr should contain searchPtr + 1 as its first argument.] Page 2 of 2 528 words 單 昂- + 100% 11:12 AM O Type here to search rP ^ 4动ENG 2019-03-26

Program:

#include <stdio.h>
#include <string.h>

void main()
{
   int i;
   char line[100], string[100];
   char *searchPtr;
  
   printf("\nEnter the line of text:\n");
   scanf(" %[^\n]s",line);
   printf("\nEnter the search string:\n");
   scanf(" %[^\n]s",string);
  
   int l = strlen(string);
  
   searchPtr = strstr(line, string);
   if( searchPtr )
   {
       printf("\nFirst time: \nRemainder string: %s\n",searchPtr);
       searchPtr = strstr(searchPtr+l, string);
       if( searchPtr )
       {
           printf("\nSecond time: \nRemainder string: %s\n\n",searchPtr);
       }
       else
       {
           printf("\nSecond time not found\n\n");
       }
   }
   else
   {
       printf("\nFirst time not found\n\n");
   }
}

Execution and Output:

terminal-> gcc -o stringsearch stringsearch.c terminal-> ./stringsearch Enter the line of text: hello world!! hello universe!! Enter the search string: hello First time: Remainder string: hello world!!! hello universe!!! second time: Remainder string: hello universe!!!
