im working a decoder for my project and i need a function that includes white-space that i can originate the data(char array) into an array here is my code if any1 is curious
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133

break ;
}
}
};
int main(){
decoder one;
if (one.inputarray() == true ){
one.request();
one.switchD();
}
return 0;
}
the code i need help with is
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
bool inputarray(){
message.open ("/Users/home/Desktop/cipher/cipher/message.txt" );
message.exceptions(ifstream::badbit);
try {
for (int i = 0; i < 50; i++){
message >> notcoded[i];
}
}
catch (ifstream::failure &e){
cout << "could not open file!" ;
return false ;
}
message.close();
return true ;
}
i just need a way for it to include the whitespace within the file, because currently it does not. thankyou in advance.
