C++ PROGRAMMING QUESTION

For the code given below, what is the output and the value of variable d after execution when using the following 4 variable initialization options. Explain your answers (notice there are no spaces within the strings): char a[]=\"way\"; char b[]=\"whey\"; char a[]=\"whey\"; char b[]=\"way\"; char a[]=\"one, two, three\"; char b[]=\"one, two, three\"; char a[]=\"I\'mGonnaGoMyWay\"; char b[]=\"I\'mGonnaGoMyWaY\"; int main() {char a[]=\"_\"; char b[]=\"_\"; string c; int d=strcmp(a, b); if (d) c=\" NOT \"; else c=\" \"; cout

Solution

for option a output is

Strings are NOT the same! because way is lexicographically smaller than whey. hence the value returned will be <0 which is true for if statement.

for option b output is

Strings are NOT the same! because whey is lexicographically greater than way. hence the value returned will be >0 which is true for if statement.

for option c output is

Strings are the same! because both the string are equal and strcmp will return 0 when both strings are equal hence the if statement evaluates to false..

for option d output is

Strings are NOT the same! because I\'mGonnaGoMyWay is lexicographically greater than I\'mGonnaGoMyWaY. hence the value returned will be >0 which is true for if statement.
