The candidates are numbered 1 to 5 and the voting is done by marking the candidate number on the ballot paper. Write a program to read the ballots and count the votes cast for each candidate using an array variable count. In case, a number read is outside the range 1 to 5, the ballot should be considered as a 39。spoilt ballot39。 and the program should also count the number of spoilt ballots. 6/2/2022 Chapter 7 Arrays main ( ) { int count, candidate[6]={0}, spoilt = 0。 printf ( Please input the votes (1~5) and press 39。039。 to end the voting.\n )。 scanf ( %d, amp。count )。 while ( count ) { if ( count =1 amp。amp。 count = 5) candidate[count] ++。 else spoilt ++。 scanf ( %d, amp。count )。 } printf ( The result of voting:\n )。 for ( count = 1。 count = 5。 count ++ ) printf(Candidate%3d ballots: %d \n,count,candidate[count])。 printf ( Spoilt ballots: %d\n, spoilt )。 } 6/2/2022 Chapter 7 Arrays The following set of numbers is popularly known as Pascal39。s triangle.
