Given two strings st1[], and st2[], implement a logic to compare the two strings, without using the string.h library and it’s functions. Concentrate on your array logic, variables, and printf() statements. Assume both the strings are already declared and defined, and the size of input string is unknown. Sample output: For example, if st1[] = “Hello, How are you.” and st2[] = “Welcome to UTSA…” The strings are unequal.   Note: Using library string functions will give NO points.

What statement is actually compiled if we use following preprocessor directives? #define SCORE 3 + 4 int value = SCORE * 15;

For this output, how many leading spaces will be printed front of this number? int x = 15; printf( “%8d”, x );

Write a logic that prints the following pattern (a diamond), based on the input value for N. Concentrate on your loop logic, variables, and printf() statements. Hint: Each line has some spaces, and some *s; and each element is of width 3. For example, for N = 5: Row 1: Element-1, and element-2 are spaces (each of width 3, i.e., 3 spaces). Element-3 is a * (of width 3, i.e., a space, a *, and a space). Row 2: Element-1 is space, Element-2 is *, Element-3 is space, Element-4 is *. Row 3: Element-1 is *, Element-2 is space, Element-3 is *, Element-4 is space, Element-5 is *. Row 4: Repeat Row-2 logic. Row 5: Repeat Row-1 logic. Once you come up with a formula, the implementation should be a cakewalk.   If N = 3, it should print        *         *     *        *   If N = 5, it should print           *            *     *     *     *     *        *     *              *  

For this array: int a[  ] = { 0, 1, 2, 3, 4 } What is the length of this array?

Given two matrices (2-D array) of elements, implement a logic to print the difference of the matrix. Hint: It’s not subtraction. I’m asking for difference, hence no negative values in result. Concentrate on your array logic, variables, and printf() statements. Assume the array is already declared and defined, and is of size SIZExSIZE. int array[][] = {{row of elements}, {row of elements}, … , {row of elements}}; Sample output: For example if array1[][] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}; array2[][] = {{9, 8, 7}, {6, 5, 4}, {3, 2, 1}}; The difference of the matrix is: 8 6 4 2 0 2 4 6 8

Which of the following statements are true about this array traversal code? int array[ 4 ] = { 35, 17, 28, 15 };int x; for( x = 0; x < 24; x++ ) {   printf( "%d\n", array[ x ] ); }
