Question:

What is the size (in bytes) of the character string declared below, char a[100];

Inactive
Pranjal K.

The size of primitive data-type char in C programming is 1 byte. A declaration of form char a[n]; declares a string of size n, i.e. a string which can accomodate at most n characters. Looking at the string declaration in the question, we can see that the string 'a' can accomodate a maximum of 100 characters. So, the size of the variable 'a' is, 100*1 byte=100 bytes

Question:

Solve the equation for x, 4x+3=2x+5

Given equation is: 4x+3=2x+5 Subtracting 2x from both sides, 4x+3-2x=2x+5-2x 2x+3=5 Subtracting 3 from both sides, 2x+3-3=5-3 2x=2 Dividing both sides by 2, 2x/2=2/2 x=1
