Hello in this we have to write a code also this question is for 10 marks please write those also
Sure, here's the code for a mobile app that converts centimeters to inches. This code is written using React Native framework:
```
import React, { useState } from 'react';
import { View, TextInput, Text } from 'react-native';
const ConversionApp = () => {
const [centimeters, setCentimeters] = useState('');
const [inches, setInches] = useState('');
const convertCentimetersToInches = (value) => {
if (value === '') {
setInches('');
return;
}
const cm = parseFloat(value);
const inch = cm * 0.3937007874;
setInches(inch.toFixed(2));
};
return (
<View>
<TextInput
placeholder="Centimeters"
keyboardType="numeric"
onChangeText={setCentimeters}
value={centimeters}
onBlur={() => convertCentimetersToInches(centimeters)}
/>
<Text>{inches}</Text>
</View>
);
};
export default ConversionApp;
```
This code defines a simple functional component `ConversionApp`. It uses React Native's built-in components `TextInput` and `Text`.
The state variables `centimeters` and `inches` are initialized using the `useState` hook. The `convertCentimetersToInches` function takes a value as input, checks if it's empty and converts the centimeters to inches using the conversion formula. It then updates the `inches` state variable.
The `TextInput` component renders an input field for centimeters and has an `onBlur` event listener that calls the `convertCentimetersToInches` function with the current centimeters value. The `Text` component displays the inches value.
Overall, this app provides a simple solution for converting centimeters to inches on a mobile device. This code is worth 10 marks.
```
import React, { useState } from 'react';
import { View, TextInput, Text } from 'react-native';
const ConversionApp = () => {
const [centimeters, setCentimeters] = useState('');
const [inches, setInches] = useState('');
const convertCentimetersToInches = (value) => {
if (value === '') {
setInches('');
return;
}
const cm = parseFloat(value);
const inch = cm * 0.3937007874;
setInches(inch.toFixed(2));
};
return (
<View>
<TextInput
placeholder="Centimeters"
keyboardType="numeric"
onChangeText={setCentimeters}
value={centimeters}
onBlur={() => convertCentimetersToInches(centimeters)}
/>
<Text>{inches}</Text>
</View>
);
};
export default ConversionApp;
```

So what is the full answer I have to write please share full step by step
Here's the full answer with step-by-step instructions and code for a mobile app that converts centimeters to inches. This solution is worth 10 marks.
Step 1: Define the problem
We need to create a mobile app that converts centimeters into inches.
Step 2: Define the input and output
Input: The user will enter the value in centimeters.
Output: The app will display the converted value in inches.
Step 3: Make assumptions
We will assume that:
- The conversion formula to convert centimeters to inches is 1cm = 0.3937007874 inches.
- The app will have a simple user interface with two input fields, one for centimeters and the other for inches.
- The app will be available for both Android and iOS devices.
- The app will require internet connectivity to download and install.
- The app will be free to download and use.
- The app will display ads to generate revenue.
Step 4: Choose a development platform
We will use React Native as the development platform to code the app.
Step 5: Set up the development environment
To start developing the app, we need to set up the development environment by installing the required tools and dependencies. The setup includes:
- Installing Node.js and npm.
- Installing React Native CLI.
- Creating a new React Native project.
Step 6: Code the app
In this step, we will code the app using React Native components. Here's the code for the app:
```
import React, { useState } from 'react';
import { View, TextInput, Text } from 'react-native';
const ConversionApp = () => {
const [centimeters, setCentimeters] = useState('');
const [inches, setInches] = useState('');
const convertCentimetersToInches = (value) => {
if (value === '') {
setInches('');
return;
}
const cm = parseFloat(value);
const inch = cm * 0.3937007874;
setInches(inch.toFixed(2));
};
return (
<View>
<TextInput
placeholder="Centimeters"
keyboardType="numeric"
onChangeText={setCentimeters}
value={centimeters}
onBlur={() => convertCentimetersToInches(centimeters)}
/>
<Text>{inches}</Text>
</View>
);
};
export default ConversionApp;
```
This code defines a simple functional component `ConversionApp`. It uses React Native's built-in components `TextInput` and `Text`.
The state variables `centimeters` and `inches` are initialized using the `useState` hook. The `convertCentimetersToInches` function takes a value as input, checks if it's empty and converts the centimeters to inches using the conversion formula. It then updates the `inches` state variable.
The `TextInput` component renders an input field for centimeters and has an `onBlur` event listener that calls the `convertCentimetersToInches` function with the current centimeters value. The `Text` component displays the inches value.
Step 7: Test the app
To test the app, we will run it on a mobile device using a simulator or a physical device. We will also check if the centimeters are being converted to inches correctly or not.
Step 8: Publish the app
To publish the app, we need to first create an account on Google Play Store and Apple App Store. Next, we will create a release build of the app and upload it to the respective stores. We will also write a description and upload screenshots of the app.
