Thread: Reading in data from Text file

i just need that for loop to work in the method i dunno what i need to add to it to get it working

atm i aint really worried bout the buffer ect atm im trying to get this function working

It would also help if you describe what actually goes wrong (e.g. it doesn't find the right city).

ok ill start it off simple

this is my function

Code:

void places()
{
   char pos[2][16];
   char place[11][11];
   int point[2];
   int i, x, wrong, flag;
   for(i=0;i<2;i++) // loops round  twice allowing the input of 2 points
            {
                 if(wrong!=1)
                 {           
                    if(i==0){printf("\n Please enter your Start point: ");} // input first point 
                    if(i==1){printf("\n Please enter your Finishing point: ");} // input first point  
                    
                 }  
                    wrong=0;  
                    scanf("&#37;16s", pos[i]);
                    size_t x;  
                          flag = 0;
                          for(x = 0; x < sizeof(place) / sizeof(*place); x ++) 
                            {
                               if(strcmp(place[x+1], pos[i])==0)
                               {
                               point[i] = x;
                               flag=1;
                               }
                            }
                            if(flag==0)
                            {
                               printf("\n Invalid place name please re enter: ");
                               i--;
                               wrong=1;       
                            }
            }

This is how i call it

Code:

places();

and this is my output:

it deosnt recognize any valid places which are input


thats what i have for a starter

ive been playing around with all sorts of ways but still i get nothing

Code:

char 2points( char place[11][11], int point[2], char pos[2][16])
{
    
    int x, wrong, flag
   for(i=0;i<2;i++) // loops round  twice allowing the input of 2 points
                {
                    if(wrong!=1) // if wrong is 0 it will out put the following
                    {
                        if(i==0){printf("\n Please enter your Start point: ");} // input first point
                        if(i==1){printf("\n Please enter your Finishing point: ");} // input first point
                        
                    }
                    wrong=0;  // set wrong to 0
                    scanf("%16s", pos[i]);
                    flag = 0; // sets flag to 0 so place is invalid until found
                    for(x = 0; x < sizeof(place); x ++) {
                        if(strcmp(place[x+1], pos[i])==0) {
                            // place found
                            point[i] = x; // point at position i is set to the value of x
                            flag=1; //sets flag as 1 because its a valid place
                        }
                    }
                    if(flag==0) // place not found
                    {
                        printf("\n Invalid place name please re enter: ");
                        i--; // decrements i by 1 sooo it will loop round again
                        wrong=1;   // sets wrong to 1 so the ask for start or finsh point is not asked for again
                    }
                }
   }

it runs but when i put in a a valid place name it doesnt find it

sooo far for the method i have just put it in like this and well called upon it

Code:

void places(char pos[2][16], int point[2], char place[11][11])
{
   int i, x, wrong, flag;

   for(i=0;i<2;i++) // loops round  twice allowing the input of 2 points
            {
                 if(wrong!=1)
                 {           
                    if(i==0){printf("\n Please enter your Start point: ");} // input first point 
                    if(i==1){printf("\n Please enter your Finishing point: ");} // input first point  
                    
                 }  
                    wrong=0;  
                    scanf("%16s", pos[i]);
               size_t x;  
                          flag = 0;
                          for(x = 0; x < sizeof(place) / sizeof(*place); x ++) 
                            {
                               if(strcmp(place[x+1], pos[i])==0)
                               {
                               point[i] = x;
                               flag=1;
                               }
                            }
                            if(flag==0)
                            {
                               printf("\n Invalid place name please re enter: ");
                               i--;
                               wrong=1;       
                            }
            }

and well im getting no strcmp and anything it wont see valid place names anyone have any reading material
