Modify the following code to make it pointer implementation of stack in C language: #include #include #include char data[100][100]; // 2d char array to store all the input data int count = 0,u_count=0; // count is the universal counter,u_count undo counter // making count -- and u_count++ if count >0 void undo() { if(count>0) { count --; u_count ++; } } // making count++ if count < 99 and undo count > 0 void redo() { if(count<99 && u_count > 0) { count++; u_count --; } } //Printing upto the counter from the data char array void print() { for(int i =0;i "); gets(inp); if(!strcmp(inp,"undo")) undo(); else if(!strcmp(inp,"redo")) redo(); else if(!strcmp(inp,"print")) print(); else if(!strcmp(inp,"save")) save(); else if(!strcmp(inp,"quit")) exit(0); else add(inp); } }
