Write a function that converts a string into an int. Assume the int is between 10 and 99. Do not use the atoi() or the stoi() fu

Liula [17]

Answer:

Written in C++

#include <iostream>

#include <sstream>

using namespace std;

int main() {

string num;

cout<<"Enter a number: ";

cin>>num;

stringstream sstream(num);

int convertnum = 0;

sstream >> convertnum;

cout << "Output: " << convertnum;

}

Explanation:

Without using atoi() or stoi(), we can make use of a string stream and this is explained as follows:

This line declares a string variable num

string num;

This line prompts user for input

cout<<"Enter a number: ";

This line gets user input

cin>>num;

This line declares a string stream variable, sstream

stringstream sstream(num);

This line declares and initializes the output variable, convertnum to 0

int convertnum = 0;

The stream is passed into the output variable, convertnum

sstream >> convertnum;

This line displays the output

cout << "Output: " << convertnum;

Note that: if user enters a non integer character such as (alphabet, etc), only the integer part will be convert.

For instance,

40a will be outputted as 40

Autonomous learners have a vast array of learning strategies in their toolboxes to choose from, most of which are effective in a

sergij07 [2.7K]

Answer:

True

Explanation:

Autonomous learners are individuals who take control of their own learning, either independently or in collaboration with others, and do not rely on teachers. Therefore based on the information provided within the question it can be said that the statement is completely true. Since they take control of their own learning, they use a variety of different techniques and tools that best suite their learning methods.

Write programs for two MSP430 boards to do the following:

Rainbow [258]

Answer:

Explanation:

#include "msp430g2553.h"

#define TXLED BIT0

#define RXLED BIT6

#define TXD BIT2

#define RXD BIT1

const char string[] = { "Hello World\r\n" };

unsigned int i; //Counter

int main(void)

{

WDTCTL = WDTPW + WDTHOLD; // Stop WDT

DCOCTL = 0; // Select lowest DCOx and MODx settings

BCSCTL1 = CALBC1_1MHZ; // Set DCO

DCOCTL = CALDCO_1MHZ;

P2DIR |= 0xFF; // All P2.x outputs

P2OUT &= 0x00; // All P2.x reset

P1SEL |= RXD + TXD ; // P1.1 = RXD, P1.2=TXD

P1SEL2 |= RXD + TXD ; // P1.1 = RXD, P1.2=TXD

P1DIR |= RXLED + TXLED;

P1OUT &= 0x00;

UCA0CTL1 |= UCSSEL_2; // SMCLK

UCA0BR0 = 0x08; // 1MHz 115200

UCA0BR1 = 0x00; // 1MHz 115200

UCA0MCTL = UCBRS2 + UCBRS0; // Modulation UCBRSx = 5

UCA0CTL1 &= ~UCSWRST; // **Initialize USCI state machine**

UC0IE |= UCA0RXIE; // Enable USCI_A0 RX interrupt

__bis_SR_register(CPUOFF + GIE); // Enter LPM0 w/ int until Byte RXed

while (1)

{ }

}

#pragma vector=USCIAB0TX_VECTOR

__interrupt void USCI0TX_ISR(void)

{

P1OUT |= TXLED;

UCA0TXBUF = string[i++]; // TX next character

if (i == sizeof string - 1) // TX over?

UC0IE &= ~UCA0TXIE; // Disable USCI_A0 TX interrupt

P1OUT &= ~TXLED; }

#pragma vector=USCIAB0RX_VECTOR

__interrupt void USCI0RX_ISR(void)

{

P1OUT |= RXLED;

if (UCA0RXBUF == 'a') // 'a' received?

{

i = 0;

UC0IE |= UCA0TXIE; // Enable USCI_A0 TX interrupt

UCA0TXBUF = string[i++];

}

P1OUT &= ~RXLED;

}
