Thread: Adding values to array in a for loop

Am very close to working out all the kinks and need help with one last thing. This code is a simplified version of what am going to do.

Code:

int main()
{
    char string1[] = "abc";
    char string2[] = "abd";
    int i,k;
    for(i=0; i<3; i++){
    for(k=0; k<3; k++){
    if(string1[i] == string2[k]){

    printf("%c", string2[k]);
                                          <----------------------- THIS IS WHERE I want the array to take in the values that pass the if statement. 

    }
    }


    }

    return 0;
}

Now I can't just place a simple array in there since its in a for loop, every time a new value passes the if statement the array will only get overwritten. Basically I need to keep stacking values into an array in a loop but not every time the loop is run. How can this be done?

Your question is not clear.

but if, as far i understood,you want to enter values when ever your if statement is true.
for eg.

Code:

 
for(i=0;i<n;i++)
  { if(statement)
      { scanf("%c",a[i]);

        }

    }

above when your if is true you enter a value, else loop continues.

I tried to tell what i thought you are looking for.

if not helpful paste your code and tell what exactly you want to do.
