copied!<p>The following code may be useful:</p> <pre><code>int t1,t2; double t3;//global variables... void parse_Vertex_Line(char *str) { int tmp=0; char *p=str; //extract the vertex-id while(*p >='0' && *p <='9') tmp = tmp*10 + *(p++) -'0'; t1=tmp; tmp=0; p++; //now extract the vertex-name.. while(*p >='0' && *p <='9') tmp = tmp*10 + *(p++) -'0'; t2=tmp; return; } void parse_Edge_Line(char *str) { //extracting the first two numbers is just the same... int tmp=0; char *p=str; //extract the first vertex-id while(*p >='0' && *p <='9') tmp = tmp*10 + *(p++) -'0'; t1=tmp; tmp=0; p++; //now extract the second vertex-id.. while(*p >='0' && *p <='9') tmp = tmp*10 + *(p++) -'0'; t2=tmp; p++; //but extracting a double value is a bit different... //extract the weight... int before_decimal=0, after_decimal=0; while(*p!='.') before_decimal = before_decimal*10 + *(p++) -'0'; p++; int no_of_digits=0; while(*p>='0' && *p<='9') { after_decimal = after_decimal*10 + *(p++) -'0'; no_of_digits++; } //assign it to the global double variable... t3 = before_decimal + (after_decimal/pow(10.0, no_of_digits)); } </code></pre> <p>Now what you do is first get the <code>number of vertices(n)</code>. Next read each of the <code>n</code> lines. Calling the function <code>parse_Vertex_Line</code> each time. Then read the <code>number of edges</code> and similarly call <code>parse_Edge_Line</code> each time. Extract the values and Store them.</p> <p>This code works for almost any delimiters. Hope this looks elegant to you. </p>
