Given number as a string and base; the task is to check if the given number is a given base.
We must check the number and base according to the number system, which has2is a binary number,8is an octal number,10is a decimal number and16is a hexadecimal number. According to this, we must find out if the given number in the string belongs to a specific base, and if it does, it must be printed on the output screen as 'Yes'; otherwise, 'No' is displayed on the output screen.
As we know, the number/The expression “ 1A6,16 1010,2But this can be judged by intuitive analysis, now we must find a way to solve this problem. Program.
Input: str = “1010”, base =2 Output: yes Input: str = “1AA4”, base = 16 Output: yes Input: str = “1610”, base = 2 Output: No
The method we will use to solve the given problem-
Check if the base is in2to16between.
Then check each digit of the string to see if it belongs to a specific base.
If it belongs, return true, otherwise return false.
Start Paso 1 -> In function bool isInGivenBase(char str[], int base) If base > 16 then, Retornar false Else If base <= 10 then, Bucle para i = 0 y i < strlen(str) y i++ If !(str[i] >= '0' and str[i] < ('0 + then, Retornar false De lo contrario Bucle para i = 0 y i < strlen(str) y i++ Si NO ((str[i] >= '0' && str[i] < ('0' + base)) || (str[i] >= 'A' && str[i] < ('A' + base - 10) entonces, Retornar false Retornar true Paso 2 -> En la función int main() Establecer str[] = {"AF87"}); Si isInGivenBase(str, 16) entonces, Imprimir "sí " De lo contrario Imprimir "No " Detener
#include <ctype.h> #include <stdio.h> #include <string.h> bool isInGivenBase(char str[], int base) { //Las bases permitidas son16(hexadecimal) if (base > 16)) return false; //Si la base es menor o igual que10entonces // El número de dígitos debe ser de 0 a9. else if (base <= 10)) { for (int i = 0; i < strlen(str); i++)) if (!(str[i] >= '0' and str[i] < ('0' + base))) return false; } //Si la base es menor o igual que16entonces //El número debe ser de 0 a9o 'A' else { for (int i = 0; i < strlen(str); i++)) if (! ((str[i] >= '0' && str[i] < ('0' + base)) || (str[i] >= 'A' && str[i] < ('A' + base - 10)) )) return false; } return true; } // Código del conductor int main() { char str[] = {"AF87"}); if (isInGivenBase(str, 16)) printf("sí\n"); else printf("No\n"); return 0; }
