-I'm trying to create a very basic translator in c (greek to english). I have a specific table to match character:
Α=A, Β=V, Γ=G, Δ=D, Ε=E, Ζ=Z, Η=H, Θ=8, Ι=I, Κ=K, Λ=L, Μ=M, Ν=N, Ξ=KS, Ο=O, Π=P, Ρ=R, Σ=S, Τ=T, Υ=Y, Φ=F, Χ=X, Ψ=PS, Ω=W.
Basically I want to translate iso8859-7 characters to iso8859-1 characters
#include <stdio.h>
#include <wchar.h>
#include <locale.h>
#include <string.h>
char map_table_capital[] = {'a', 'v', 'g', 'd', 'e', 'z', 'h', '8', 'i', 'k', 'l', 'm', 'n', 'ks', 'o', 'p', 'r', 's', 't', 'y', 'f', 'x', 'ps', 'w'};
int main() {
setlocale(LC_ALL, "el_GR.ISO8859-7");
printf("Enter a string of Greek alphabet characters: ");
char input[100];
scanf("%s", input);
int length = strlen(input);
int i;
for (i = 0; i < length; i++) {
if (input[i] >= '\u03B1' && input[i] <= '\u03C9') {
int index = input[i] - '\u03B1';
input[i] = map_table_capital[index];
}
}
printf("Mapped string: %s\n", input);
return 0;
}
My problem is that whatever input I give ('α') I have the same output ('α') when I should get ('a')
So input: 'αβγ', should have as output: 'avg'. But I get as output: 'αβγ'
Τhe compiler gives me a warning about having 'ks' and 'ps' but I don't know how to fix it, also its giving a warning about "multi-character character constant" about the:
if (input_string[i] >= '\u03B1' && input_string[i] <= '\u03C9') {
int index = input_string[i] - '\u03B1';
\u03B1 and \u03C9 which are basically 'α' and 'ω'. I tried basing this code of a simillar one that just reverses the english alphabet:
#include <stdio.h>
#include <string.h>
int main() {
char input[100];
char map_table[26] = {'z','y','x','w','v','u','t','s','r','q',
'p','o','n','m','l','k','j','i','h','g',
'f','e','d','c','b','a'};
int i;
printf("Enter a string: ");
fgets(input, sizeof(input), stdin);
int length = strlen(input);
for (i = 0; i < length; i++) {
if (input[i] >= 'a' && input[i] <= 'x') {
int index = input[i] - 'a';
input[i] = map_table[index];
}
}
printf("Mapped string: %s", input);
return 0;
}
If anyone has any idea I'd really appriciate it, thanks a lot!
EDIT1: I've gone a completly different route with the code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_LEN 8
int main() {
char input_letter[MAX_LEN];
char *mapping_table[] = {"A", "V", "G", "D", "E", "Z", "H", "8", "I", "K", "L", "M", "N", "KS", "O", "P", "R", "S", "T", "Y", "F", "X", "PS", "W"};
char *greek_alphabet[] = {"Α", "Β", "Γ", "Δ", "Ε", "Ζ", "Η", "Θ", "Ι", "Κ", "Λ", "Μ", "Ν", "Ξ", "Ο", "Π", "Ρ", "Σ", "Τ", "Υ", "Φ", "Χ", "Ψ", "Ω"};
printf("Enter a Greek letter: ");
fgets(input_letter, MAX_LEN, stdin);
int len = strlen(input_letter);
int num_alphabets = sizeof(greek_alphabet) / sizeof(greek_alphabet[0]);
printf("%d\n", num_alphabets);
int index = -1;
int found = 0;
for (int i = 0; i < num_alphabets; i++) {
if (strcmp(input_letter, greek_alphabet[i]) == 0 ||
strlen(input_letter) == len)) {
printf("%d\n", i);
index = i;
found = 1;
break;
}
}
if (found == 1) {
printf("Mapped to: %s\n", mapping_table[index]);
} else {
printf("Invalid input.\n");
}
return 0;
}
Now my problem is that whatever greek character I give as input the output remains 'A', basically 'i' doesn't increase
