Using seperate elements in a string array?
Sorry in advance for the wordiness :frown:
This is for a homework assignment, so i'm not asking for help on the entire thing :p , though i'm not a CS major, so it really rustles my jimmies.
The code is supposed to convert a number into words (ie 23 into twenty three)
so far, the user inputs an int, i use sprintf to write it to a char array, then send it to a function that is supposed to convert it.
Code:
#include <stdio.h>
#include <string.h>
int getNumber();
char convertToString(char *buffer);
int main()
{
char *buffer[100];
int num;
num = getNumber();
memset(buffer, '\0', 100);
sprintf(buffer,"%d",num);
printf("You typed: %s \n",buffer); //test
convertToString(buffer);
return 0;
}
int getNumber(){
int num;
do{
printf("Enter an integer less than 1000: ");
scanf("%d",&num);
}while(num<1 || num>999);
return(num);
}
char convertToString(char *buffer)
{
char *ones[]={"one ","two ","three ","four ","five","six ","seven ","eight ","nine "};
char *tens[]={"ten ","eleven ","twelve ","thirteen ","fourteen ","fifteen ","sixteen ","seventeen ","eighteen ","nineteen "};
char *twenties[]={"","twenty ","thirty ","forty ","fifty ","sixty ","seventy ","eighty ","ninety "};
char *hundreds[]={"","","one hundred ","two hundred ","three hundred ","four hundred ","five hundred ","six hundred ","seven hundred ","eight hundred ","nine hundred "};
char *temp[100];
int length = strlen(buffer);
if(length = 1)
{
strcpy(temp,ones[buffer[0]]);
}
}
Not finished yet obviously, but I hit a problem on the line with:
strcpy(temp,ones[buffer[0]]);
which is supposed to take what's in buffer[0] (the first digit of the inputted number), and tell it to copy the same index of ones (so if buffer[0] = 3, ones[buffer[0]] = three, then copy it into my temp array, which integers of length 2 or 3 would be catenated to the end.
BUT, if the user inputted number was say 34, buffer[0]=3 as i would expect, but buffer[1] is garbage. How can I fix this so the separate digits of the inputted number are in separate elements of the buffer array? Or is there an easier way to do this...?
