c++ - Comparing 8 - bit Unsigned Integer to HEX Failing -

i have c++ vector full of uint8_t values tcp data segment. looking 1 of 2 values should @ first index of vector.

i have following if statement express logic.

if ( ui8bufferin.at(0) != 0xe4 || ui8bufferin.at(0) != 0xe2){     printf("\nwe have problem, no parsing done, package type = %u\n", ui8bufferin.at(0));     proceed = false; } 

the above if statement executing when shouldn't. following printout:

we have problem, no parsing done, package type = 226 

so don't have math, 226 integer 0xe2 in hex.

i've been @ while, may simple, great!

i think might want logic be:

if ( ui8bufferin.at(0) != 0xe4 && ui8bufferin.at(0) != 0xe2){ 

as right you're saying "if either case of: (it's not 0xe4) or case of: (it's not 0xe2), have problem" - which, if understand correctly, not want say. statement, getting 0xe2, because you're not getting 0xe4 (ui8bufferin.at(0) != 0xe4), statement executes.
