Question

I have to build off of this current program in C and I am very confused on this assignment.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int roll(int x){
if (x>50 || x < 1){
return 4;
}
else{
return (rand()%(x+1));
}
}

int main(int argc, char const *argv[])
{
int A[50];

srand(time(NULL));
int k,i,sum=0,countOf7=0,consecutiveSameNums=0;

for ( k = 0; k < 50; ++k ){
A[k] = roll(10);
}

printf("first 3 values ");
for ( k = 0; k < 3; ++k )
printf("%d ", A[k]);
printf(" ");

for (i = 0; i < 50; ++i)
{
sum=sum+A[i];
}
printf("Sum : %d ",sum );

for (i = 0; i < 50; ++i)
{
if (A[i]==7)
{
countOf7++;

countOf7++;
}
}
printf("7 rolled %d times ",countOf7 );

for (i = 0; i < 49; ++i)
{
if (A[i]==A[i+1])
{
consecutiveSameNums++;
}
}
printf("%d times two consecutive same numbers rolled ",consecutiveSameNums$

return 0;
}

Assignment:

For the quiz, roll a 10-sided dice 50 times

Write each of these functions, then call appropriate so solve the requests problems

Print the values in an array:    void printArray( int A[], int N )

     A is the array of integers, N is the number of items to print

Find the sum of values in an array:   int sumArray( int A[], int N )

Frequency of value in array:   int freqArray( int A[], int N[], int T)

     A is array, N is number of item, T is target value

Utility function – make sure you have this function:

int roll( int )

Purpose: roll a dice, return the value

Params: how sides on the dice

              If # of sides is outside 1 to 50 range, return 4

Additional functions to write & test:

     Write the functions, test them, you’ll submit to the quiz

int isVowel( char )

Purpose: determine if character is a vowel, return 1 for yes, 0 for no

          Note: y is note a vowel, not even sometimes :)

Params: a character

char toGrade( int )              [ABCDF]

Purpose: convert numeric score to letter grade, standard 90-80-70…

Params: integer representing score

           If score is outside 0 to 100 legal range, return ?

int fullCartons( int )

Purpose: how egg cartons (dozen) can be filled

Params: number of eggs

void zigzag( int )

Purpose: make 1 zig-zag bump

Params: height of the zig

This is a zigzag of size 4

Explanation / Answer

here is your code : -------------->>>>>>>>>>>

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int roll(int x){
if (x>50 || x < 1){
  return 4;
}
else{
  return (rand()%x+1);
}
}

void printArray( int A[],int N){
int i;
for(i= 0;i<N;i++){
  printf("%d ",A[i]);
}
}

int sumArray(int A[],int N){
int i;
int val = 0;
for(i= 0;i<N;i++){
  val += A[i];
}
return val;
}

int freqArray(int A[],int N,int T){
int i;
int val = 0;
for(i= 0;i<N;i++){
  if(T == A[i]){
   val++;
  }
}
return val;
}

int isVowel(char ch){
if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u'){
  return 1;
}
if(ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U'){
  return 1;
}

return 0;
}

char toGrade(int grade){
if(grade >= 90){
  return 'A';
}else if(grade >= 80){
  return 'B';
}else if(grade >= 70){
  return 'C';
}else if(grade >= 60){
  return 'D';
}else{
  return 'F';
}
}

int fullCartons(int numEgg){
return numEgg/12;
}

void zigzag(int num){
int i,j;
for(i = 0;i<num;i++){
  for(j = 0;j<i;j++){
   printf(" ");
  }
  printf("# ");
}
for(i = i-2;i>=0;i--){
  for(j = 0;j<i;j++){
   printf(" ");
  }
  printf("# ");
}
}

int main(int argc, char const *argv[])
{
int A[50];
srand(time(NULL));
int k,i,sum=0,countOf7=0;
char check;
for ( k = 0; k < 50; ++k ){
A[k] = roll(10);
}
printf(" Printing the Rolled Array ");
printArray(A,50);
sum = sumArray(A,50);
printf("Sum : %d ",sum );
countOf7 = freqArray(A,50,7);
printf("7 rolled %d times ",countOf7 );
while(1){
printf(" Enter a character to check it is vowel or not : ");
scanf("%c%*c",&check);
i = isVowel(check);
if(i == 1){
  printf(" Is A Vowel.");
}else{
  printf(" Is Not A Vowel.");
}
printf(" Do you want to check more(y/n)? ");
scanf("%c%*c",&check);
if(check == 'y' || check == 'Y'){
  continue;
}else{
  break;
}
}
printf(" Enter A number to print Zig Zag : ");
scanf("%d",&i);
zigzag(i);
printf(" Enter A grade to see char equivalent : ");
scanf("%d",&i);
printf(" grade = %c",toGrade(i));
return 0;
}
