Closed About reversing

[Arcturus]

Mga Master konting tulong naman po,
May way po ba para hindi i accept ng int variable ang mga special characters?
eto po yung code:

string strrev(string reverse){
    int i,j;
    j = reverse.size() - 1;
    for( i = 0 ; i < j ; i++, j--){
        temp = reverse[i];
        reverse[i] = reverse[j];
        reverse[j] = temp;
    }
    return reverse;

int main(){
string digits;
    int TOOINT;


cout<<"Enter any Integer for Reversing: ";
               cin.ignore();
               do {
               getline(cin, digits);
               TOOINT = atoi(digits.c_str());
            }while((TOOINT / 10) < 2);
            cout<<"The Reversed of "<<digits<<" is "<<strrev(digits);
}

eto po yung output,

Ilagay mo sa loob ng try-catch code mo or yung input.

Salamat Boss, try ko po

 

[mrHazan]

Salamat Boss, try ko po

chineck ko hindi naglalabas ng exception error kahit maling input sa cin.

Try mo to. Baka makakuha ka ng idea.

#include<string>
#include<iostream>
using namespace std;

string strrev(string r){
    int temp;
    for(int i = 0,int j = r.size()-1 ; i <= j ; i++, j--)
    {
        temp = r[i];
        r[i] = r[j];
        r[j] = temp;
    }
    return r;
}
int main()
{
    int digits;
    string stringDigit;
    cout<<"Enter any Integer for Reversing: ";

    cin>> digits;
    if(!cin)
    {
        cout<< "The input is not a digit, input should be single integer without spaces...\n\n";
    }
    else
    {
        stringDigit = to_string(digits);
        cout<<"The Reversed of "<<stringDigit<<" is "<<strrev(stringDigit) << endl << endl;
    }
}

    }
}

Ganun talaga boss, basta't nag enter ako ng number na may isang letter or special char. napasok sya

 

[Arcturus]

cin>> digits; if(!cin)

Etong part na to siguro kailangan ayusin boss,

Inayos ko ulit. Kasi tumatanggap ng integer na may spaces.

Big Thanks Boss!
Ayos na sya )

Sure..
Meron akong thread : https://phcorner.net/threads/615584/

Pero gusto ko, may progress ka hindi yung sa akin ka magpapagawa. Tulad nito may gawa ka na, ganun tapos may nahihirapan kang part. I will be willing to help.

Thaaaanks boss )

Master sa code nyo po na

bool IntegerChecker(string input);

Pwede po bang mag declude ng dot(.) ?
balak ko din po kasing gamitin yung code nyo po na yan sa isa pang program na e^x na naka double variable po, hindi po kasi nya tinatanggap ang dot(.) kaya kahit mag enter ako ng 12.12 auto block syaa,

Medyo complicated na yan kasi ichecheck mo kung digits lang at isang dot lang ang nageexist sa string.

bool FloatChecker(string input)

    int dotCount = 0;

    {

Astig mo talaga boss!, ang daming knowlege galing sayo!

 

[mrHazan]

másáráp sa feeling kapag nakakasolve ka ng mga programming problems ng sariling sikap. Sana kayo din i-try niyo bago kayo humingi ng tulong sa iba.

 

[siesta]

#include <stdio.h>

int main() {
    int d;

    printf("Enter integer: ");
    scanf("%d",&d);
    
    printf("Reverse: ");
    do {
        printf("%d",d%10);
        d/=10;
    } while(d>0);

    return 0;
}
