Thread: Basic Data types help

Hey, can anyone tell how to writea program that translates an alphabetic phone number into a numeric form
I tried many things and I don't know what to do
Please help me, I am clueless in this

this is what I have so far for the program. I don't know what to do next

/*This program translates an alphabetic phone phone number into numeric form*/

#include <stdio.h>
int main()
{
char letter=0;
int number=0:
printf("Enter a phone number in letters: \n");
scanf("%c, &letter);
fflush (stdin);
letter = getchar();

this will actually do the work for you

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

/* Call this with the actual data, it will return the phone number. */
int alpha2number(char data[]) {
    char value[ strlen(data) ]; /* Store data here. */
    
    int x = 0; /* Keep track of where we are. */
    
    while(data[x] != '\0') {
        switch(data[x]) { /* Parse threw the data. */
            case 'a': /* All of these are 2. */
            case 'b':
            case 'c':
                value[x] = 2;
            /* Keep it going here, im to lazzy. */
        }
        
        ++x; /* Go to next letter*/
    } /* Start all over again untill theres no more data left. */
    
    return atoi(value); /* I cheated and added the phone number to a string, here we take my string and return a number that can be used. Im lazzy, so i didnt do the math. */
}

what you wrote for it has the right idea, but it needs some work. think about what your doing.

get a string, parse it with a function, take the resaults back, print it.

o yeah, you know your homework is just going to get harder right?

Code:

int alpha2number(char data[]) {
    char value[ strlen(data) ]; /* Store data here. */
    /* ... */
}

Until C99 implementations are more readily available, it might be better to post a C90 solution. Or at least comment that this code is C99 (or C++, but then that would be off-topic on this board).

Dave_Sinkula, your completly right here, but do you know how many people have told me that before.

im i the only one that hasnt memorized this stuff!!!!!
