- Define a C++ language float literal using regular expression. A float literal in C language has an optional exponent part. If a float literal is written without exponent part, then it must have a decimal point which can appear at the start, at the end or in the middle of digits, as in following examples: 123.456 .456 456. If float literal is written with exponent, then decimal point in mantissa part is optional, and exponent is a whole number with optional sign, as in following examples: 123e78 123e+78 123e-78 123.456e78 .456e78 456.e78Define a C++ language float literal using regular expression.

I did encounter and solve this problem with Java but I cannot seem to implement the use of structures in solving this problem. Help is appreciated, thank you. Using the concept of structures, write a program to assign passenger seats in an airplane. Assume a small airplane with seats numbered as follows: 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D The program should display the seat pattern, marking with an ‘X’ the seats already assigned. For example, after seats 1A, 2B, and 4C are taken, the display should look like: 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D Seats are assigned by specifying a number and a letter. If the user types in a seat that is already assigned, the program should say that the seat is occupied and ask for another choice. The program should run until all seats are…debug c language main() { int m,n; for(i 0; i << 5; i++) { printf("\t\t\t\t"); for(j 0; j << 5; j+++) printf("*"); printf("/n"); }
