    switch(code) {
        case 1: price = 3,500.00;
                break;
        case 2: price = 2,500.00;
                break;
	    case 3: price = 4,500.00;
		        break;
        case 4: price = 500.00;
                break;
		case 5: price = 750.00;
		        break;
		case 6: price = 1,500.00;
    }
    amt = price * qty;
    printf("\nAmount\t\t: %.2f", amt); 
    
    totalAmt = totalAmt + amt;
    printf("\nTotalAmount\t: %.2f", totalAmt);
    
    printf("\nAdd another oder(y/n)? ");
    addAnother = getchar();
    }while(addAnother == 'y' || addAnother == 'Y');
    
    do{
        printf("\nCash Tendered\t: ");
    scanf("%f", &cash);
    }while(cash < totalAmt);
        
    
    change = cash - totalAmt;
    printf("\nChange\t\t: &.2f", change);

What I have tried:

#include <stdio.h>

void main (void)  {
    int code, qty;
    float price, amt, totalAmt, cash, change;
    char addAnother;
    
    // do-while loop -> post-test
    // while loop -> pre-test
    // for loop -> pretest
    
 do {
    system("cls");
    printf("======================\n");
    printf("computer\n");
    printf("=======================\n\n");
    printf("[1] HP Pavilion\t\tphp 3,500.00\n");
    printf("[2] ChromeBook\t\tphp 2,500.00\n");
	printf("[3] Acer Aspire\t\tphp 4,500.00\n");
    printf("[4] HP Ram 16GB\t\tphp 500.00\n");
	printf("[5] chromeBook Ram 32GB\t\tphp 750.00\n");
	printf("[6] Acer Ram 64GB\t\tphp 1,500.00\n");
    
    printf("\nEnter Code\t: ");
    scanf("%d", &code);
    printf("nEnter Quantity\t:");
    scanf("%d", &qty);
    
    switch(code) {
        case 1: price = 3,500.00;
                break;
        case 2: price = 2,500.00;
                break;
	    case 3: price = 4,500.00;
		        break;
        case 4: price = 500.00;
                break;
		case 5: price = 750.00;
		        break;
		case 6: price = 1,500.00;
    }
    amt = price * qty;
    printf("\nAmount\t\t: %.2f", amt); 
    
    totalAmt = totalAmt + amt;
    printf("\nTotalAmount\t: %.2f", totalAmt);
    
    printf("\nAdd another oder(y/n)? ");
    addAnother = getchar();
    }while(addAnother == 'y' || addAnother == 'Y');
    
    do{
        printf("\nCash Tendered\t: ");
    scanf("%f", &cash);
    }while(cash < totalAmt);
        
    
    change = cash - totalAmt;
    printf("\nChange\t\t: &.2f", change);

I need help to create a store to keep track of computer with computer brand and model ram and ram size to display
1: Display the tota; and average price of all computer
2: display the brand of the most expensive computer

Variables data type
basic input/output
logic(if else if statements
loops( for, while, or do-while. hint: data has to be processed within the loop)

While you have not actually asked a question, there are several issues with your code. Here are a few of them.

C++

case 6: price = 1,500.00;

price is a floating point value and floats can not have commas embedded in them. They must be written without the comma like this :

C++

case 6: price = 1500.00;

The previous five prices must also be written without commas.

I like to use toupper or tolower so I only have to check a character's value one time. That can look like this :

C++

    addAnother = getchar();
    addAnother = tolower( addAnother );
} while( addAnother == 'y' );

One other thing I noticed is the format specifier for one of your printf statements is incorrect. It should look like this :

C++

printf("\nChange\t\t: %.2f", change);

with a percent sign instead of an ampersand.
