Opa galera, tudo bem ? Este código está passando pelo tabela ASCII inteira, gostaria de mudar para as letras de A à Z. #include <stdio.h> #include <string.h> int main(void) { char mess[100]; printf("Enter encoded message: "); scanf("%s", mess); char key[100]; printf("Enter the key: "); scanf("%s", key); //converting string into ascii values and storing into array mess int i; int messlen = strlen(mess); for (i = 0; i < messlen; i++) { mess = mess - 64; //printf("%d\n", mess); } //converting key into ascii values int keylen = strlen(key); for (i = 0; i < keylen; i++) { key = key - 64; } //decoding char ans[100]; int count = 0; i = 0; while (i < messlen) { //if (mess == 1) //{ // ans += 1; //} if (mess < key[count]) { ans = (mess - key[count] + 26) + 64; printf("%c", ans); } else if (mess > key[count]) { ans = (mess - key[count]) + 64; printf("%c", ans); } if (count == keylen -1) { count = -1; } count += 1; i += 1; } printf("\n"); return(0); }
