c++ - comparing characters causes a bus error -

i'm lost trying figure out runtime error. have struct datatype, , implementation of in array items[]. in struct, there char name defined. i'm reading user input using cin char datatype.

i=0; { printf("%c\n", items[i].name); printf("%c\n", itemname);  //if ( items[i].name == itemname )  //found=true; i++; } while (i<numofitems || found); 

if uncomment if statement, printf("%c\n", itemname); seems run thousands of times followed bus error: 10. note numofitems current 5.

output way written:

a c b c c c d c e c 

any idea why can't compare if 1 char equivalent another?

your condition should i<numofitems && !found. right now, if either true, keeps looping, , found becomes true on third iteration.

i'd rewrite this:

for (int = 0; <numitems; ++i)     std::cout << items[i].name << '\n';     std::cout << itemname << '\n';      if ( items[i].name == itemname )          break; }
