    copied!<p>The problem is that I can decode a data stream for the first time, but then it will become an infinite loop and display the same value over and over again... I'm using borland C++. Decoding is done by first saving the text a to z in an array, then taking the input data stream and then cutting the contents of the array using strcpy then comparing with the contents of the first array then if a match is found, the corresponding ASCII is printed. </p> <p>code:</p> <pre><code>#include&lt;conio.h&gt; #include&lt;iostream.h&gt; #include&lt;string.h&gt; #include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; using namespace std; int codes[512]; char cut_stream[100]; char input_stream[100]; char decoded_stream[256]; int test,count,cut_start,cut_end,length_of_stream,final,temp_loop_s,temp_loop_e,temp_num,comp_num,send; void select_num(int select) { int output; output = select + 64; cout &lt;&lt; char(output); } void decode() { cout&lt;&lt;"\nEnter the data stream ";//&lt;&lt;endl; cin &gt;&gt; input_stream; length_of_stream = strlen(input_stream); //cout&lt;&lt; length_of_stream ; //only for debugging /******************************************** the code starts here... ********************************************/ count = length_of_stream; //count -= count; for(int ini =0; ini&lt;=count ; ini++) { for( final=1;final&lt;=count;final++) { strncpy(cut_stream, &amp;input_stream[ini], final); //cut_start = cut_start + 1; /********************************************* compare *********************************************/ temp_num = atoi(cut_stream); for(int z= 1;z&lt;=26;z++) { comp_num = codes[z]; if(comp_num == temp_num) { send =z; select_num(send); test =1; comp_num =0; break; } } if( test ==1) { test =0; ini = final-1; // the increment will be given on the next for loop so it is reduced here //final =0; //cout&lt;&lt; "im in test"; break; } } } cout&lt;&lt; "end"; while(1); } //cout&lt;&lt; decoded_stream; //while(1); void main() { cut_start =0; cut_end = 1; cout &lt;&lt; "Huffman decoder" &lt;&lt; endl; cout &lt;&lt; "Enter the codes for a-z" &lt;&lt; endl; for(int i =1;i&lt;=3;i++) { cin &gt;&gt; codes[i]; } decode(); } </code></pre>
