Each of the following definitions and program segments has errors, Locate as many as you can.

Short Answer

Expert verified
Question: Identify and correct the errors in the given code segments. Given code: 1. int a,b,c; 2. float x = 3.1; 3. printf("The sum of %d and %d is %d", a + b, c); Corrected code: 1. int a,b,c; 2. float x = 3.1; 3. c = a + b; 4. printf("The sum of %d and %d is %d", a, b, c);

Step by step solution

01

Analyze Line 1

Line 1 declares three 'int' variables 'a', 'b', and 'c'. There is no error in this line.
02

Analyze Line 2

Line 2 declares a 'float' variable 'x' and assigns it the value 3.1. There is no error in this line as well.
03

Analyze Line 3

Line 3 has a printf statement that aims to print the sum of 'a' and 'b', and then store it in 'c'. There is a syntax error in the printf statement as it should have three variables to replace %d placeholders, but only two variables, 'a + b' and 'c', are provided. To fix this error, we should first calculate the sum of 'a' and 'b', store the result in 'c', and then use all three variables in the printf statement. Corrected line 3: c = a + b; printf("The sum of %d and %d is %d", a, b, c); Summary: - No errors found in line 1 - No errors found in line 2 - Syntax error found in line 3, which has been corrected as shown above.

True or False Pointers may be compared using the relational operators.

Each of the following definitions and program segments has errors. Locate as many as you can. const int arr[] = { 1, 2, 3 }; int *ptr = arr;

True or False When you add a value to a pointer, you are actually adding that number times the size of the data type referenced by the pointer.
