sample output that I want:

chocolate bar   $1.00
skittles        $1.20
marshmellows    $5.00
candy-cane      $0.90

the output I got:

░"@  $1.00
░"@  $1.20
░"@  $5.00
░"@  $0.90

the code I made:

#include <stdio.h>
void ShowMenu();
int main()
{
    int i, j;
    float price[4][1]= {1,1.2,5,0.9};
    char snack[4][20];
    
    ShowMenu(price, i, j, snack);
    
    return 0;
}

void ShowMenu(float price[4][1], int i, int j, char snack[4][20])
{
    for (i=0;i<4;i  )
        for (j=0;j<1;j  )
            {
            if(i==0)
            snack[0][20]=="chocolate bar" ;
            else if(i==1)
            snack[1][20]=="skittles"  ;
            else if(i==2)
            snack[2][20]=="marshmellows"  ;
            else if(i==3)
            snack[3][20]=="candy-cane"  ;
            printf("%s  RM%.2f\n", snack, price[i][j]);
            }
}

CodePudding user response：

1. Your function prototype has to be *exactly the same as your definition!!!
2. It is hard what is the purpose of many variables and parameters. I have stripped down everything not needed

void ShowMenu(float price[], char *snack[], int nitems);
int main(void)
{
    float price[4] = {1,1.2,5,0.9};
    char *snack[20] = {"chocolate bar", "skittles", "marshmellows", "candy-cane"};
    
    ShowMenu(price, snack, 4);
    
    return 0;
}

void ShowMenu(float price[], char *snack[], int nitems)
{
    for (int i = 0; i < nitems; i  )
    {
        printf("%s\tRM%.2f\n", snack[i], price[i]);
    }
}
