<u><em>Differences between barcode reader and character recognition devices:</em></u>
Barcode Reader or Barcode Scanner:
- Barcode Scanner scans the data by brightening the barcodes usingSensor
- The analog signal is then converted into digital signal by Converter.
- The Decoder calculates the converted data and sends valid data to the computer.
Character Recognition Devices (OCR):
- OCR scans the physical document and converts them into two-coloured format.
- The darker and lighter area are identified as characters and blanks respectively.
- The common methods used are: Pattern Recognition and Feature Detection.
Answer:
The following code as follows:
Code:
max=name1; //define variable max that holds name1 variable value.
if (strcmp(name2, max)>0) //if block.
{
max=name2; //assign value to max.
}
if (strcmp(name3,max)>0) //if block.
{
max=name3; //assign value to max.
}
Explanation:
In the above code, we define a variable that is max. The data type of max variable is the same as variables "name1, name2, and name3" that is "char". In the max variable, we assign the value of the name1 variable and use if block statement two times. In if block, we use strcmp() function that can be defined as:
- In first if block we pass two variables in strcmp() function that is "name2 and max" that compare string value. If the name2 variable is greater then max variable value so, the max variable value is change by name2 variable that is "max=name2".
- In second if block we pass two variables in strcmp() function that is "name3 and max" that compare string value. If the name3 variable is greater then max variable value so, the max variable value is change by name3 variable that is "max=name3".
I think this is true but like think about the computer hardware and stuff
