C Programming

1. Declare an array availablePizzas of 3 PizzaIngredients elements.

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

typedef struct PizzaIngredients_struct {
char pizzaName[30];
char ingredients[70];
} PizzaIngredients;

int main(void) {

/* Your solution goes here */

strcpy(availablePizzas[0].pizzaName, "Barbecue");
strcpy(availablePizzas[0].ingredients, "Beef, chicken, bacon, barbecue sauce");
strcpy(availablePizzas[1].pizzaName, "Carbonara");
strcpy(availablePizzas[1].ingredients, "Mushrooms, onion, creamy sauce");
strcpy(availablePizzas[2].pizzaName, "Ham and Cheese");
strcpy(availablePizzas[2].ingredients, "Ham, cheese, bacon");

printf("%s: %s ", availablePizzas[0].pizzaName, availablePizzas[0].ingredients);
printf("%s: %s ", availablePizzas[1].pizzaName, availablePizzas[1].ingredients);
printf("%s: %s ", availablePizzas[2].pizzaName, availablePizzas[2].ingredients);

return 0;
}

2. Write a statement that calls a function named IncreaseItemQty, passing the variable addQty. Assign notebookInfo with the value returned by IncreaseItemQty.

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

typedef struct ProductInfo_struct {
char itemName[30];
int itemQty;
} ProductInfo;

ProductInfo IncreaseItemQty (ProductInfo productToStock, int increaseValue) {
productToStock.itemQty = productToStock.itemQty + increaseValue;

return productToStock;
}

int main(void) {
ProductInfo notebookInfo;
int addQty = 10;

scanf("%s", notebookInfo.itemName);
scanf("%d", &notebookInfo.itemQty);

/* Your solution goes here */

printf("Name: %s, stock: %d ", notebookInfo.itemName, notebookInfo.itemQty);

return 0;
}

3. For any element in keysList with a value greater than 40, print the corresponding value in itemsList, followed by a space.
Ex: If keysList = {32, 105, 101, 35} and itemsList = {10, 20, 30, 40}, print:

#include <stdio.h>

int main (void) {

const int SIZE_LIST = 4;
int keysList[SIZE_LIST];
int itemsList[SIZE_LIST];
int i;

keysList[0] = 13;
keysList[1] = 47;
keysList[2] = 71;
keysList[3] = 59;

itemsList[0] = 12;
itemsList[1] = 36;
itemsList[2] = 72;
itemsList[3] = 54;

/* Your solution goes here */

printf(" ");

return 0;
}

Explanation / Answer

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

typedef struct PizzaIngredients_struct {
   char pizzaName[30];
   char ingredients[70];
} PizzaIngredients;

int main(void) {

// declaration goes like StructureName VariableName[NumberOfItems]
PizzaIngredients availablePizzas[3];

   strcpy(availablePizzas[0].pizzaName, "Barbecue");
   strcpy(availablePizzas[0].ingredients, "Beef, chicken, bacon, barbecue sauce");
   strcpy(availablePizzas[1].pizzaName, "Carbonara");
   strcpy(availablePizzas[1].ingredients, "Mushrooms, onion, creamy sauce");
   strcpy(availablePizzas[2].pizzaName, "Ham and Cheese");
   strcpy(availablePizzas[2].ingredients, "Ham, cheese, bacon");

   printf("%s: %s ", availablePizzas[0].pizzaName, availablePizzas[0].ingredients);
   printf("%s: %s ", availablePizzas[1].pizzaName, availablePizzas[1].ingredients);
   printf("%s: %s ", availablePizzas[2].pizzaName, availablePizzas[2].ingredients);

   return 0;
}

Output

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

typedef struct ProductInfo_struct {
   char itemName[30];
   int itemQty;
} ProductInfo;

ProductInfo IncreaseItemQty (ProductInfo productToStock, int increaseValue) {
   productToStock.itemQty = productToStock.itemQty + increaseValue;

   return productToStock;
}

int main(void) {
   ProductInfo notebookInfo;
   int addQty = 10;

   scanf("%s", notebookInfo.itemName);
   scanf("%d", &notebookInfo.itemQty);

   /* Calling function with notebookInfo and assigning the structure after incrementing the quantity */
   notebookInfo = IncreaseItemQty(notebookInfo, addQty);

   printf("Name: %s, stock: %d ", notebookInfo.itemName, notebookInfo.itemQty);

   return 0;
}

Output

#include <stdio.h>

int main (void) {

   const int SIZE_LIST = 4;
   int keysList[SIZE_LIST];
   int itemsList[SIZE_LIST];
   int i;

   keysList[0] = 13;
   keysList[1] = 47;
   keysList[2] = 71;
   keysList[3] = 59;

   itemsList[0] = 12;
   itemsList[1] = 36;
   itemsList[2] = 72;
   itemsList[3] = 54;

   /* Looping through each element
   Checking if the value is greater than 40
   printing value
   */
   for(i=0; i<SIZE_LIST; i++)
   {
      if(keysList[i] > 40)
        printf("%d ", itemsList[i]);
   }
  
   printf(" ");

   return 0;
}

Output

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

typedef struct PizzaIngredients_struct {
   char pizzaName[30];
   char ingredients[70];
} PizzaIngredients;

int main(void) {

// declaration goes like StructureName VariableName[NumberOfItems]
PizzaIngredients availablePizzas[3];

   strcpy(availablePizzas[0].pizzaName, "Barbecue");
   strcpy(availablePizzas[0].ingredients, "Beef, chicken, bacon, barbecue sauce");
   strcpy(availablePizzas[1].pizzaName, "Carbonara");

   printf("%s: %s ", availablePizzas[2].pizzaName, availablePizzas[2].ingredients);

   return 0;
}

Output

  Barbecue: Beef, chicken, bacon, barbecue sauce  Carbonara: Mushrooms, onion, creamy sauce  Ham and Cheese: Ham, cheese, bacon  

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

typedef struct ProductInfo_struct {
   char itemName[30];
   int itemQty;
} ProductInfo;

ProductInfo IncreaseItemQty (ProductInfo productToStock, int increaseValue) {
   productToStock.itemQty = productToStock.itemQty + increaseValue;

   return productToStock;
}

int main(void) {
   ProductInfo notebookInfo;
   int addQty = 10;

   scanf("%s", notebookInfo.itemName);
   scanf("%d", &notebookInfo.itemQty);

   /* Calling function with notebookInfo and assigning the structure after incrementing the quantity */
   notebookInfo = IncreaseItemQty(notebookInfo, addQty);

   printf("Name: %s, stock: %d ", notebookInfo.itemName, notebookInfo.itemQty);

   return 0;
}

Output

   Chegg   20  Name: Chegg, stock: 30  

#include <stdio.h>

int main (void) {

   const int SIZE_LIST = 4;
   int keysList[SIZE_LIST];
   int itemsList[SIZE_LIST];
   int i;

   keysList[0] = 13;
