In Linux, what is the command to remove a file?

In vim, in Command mode, what does the letter j do?

Given two strings st1[], and st2[], implement a logic to concatenate the second string to the first string, 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 concatenated string is: Hello, How are you. Welcome to UTSA…   Note: Only printing them side-by-side without concatenating, or 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;

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 ] ); }

Assume the name of your executable is myprogram. Which of the following commands will execute the program?

Predict the Output: printf(“%d”, sizeof(5.0)); printf(“%d”, sizeof(5)); Explain what is printed and why? Consider the code is fully formed, i.e., no excuses like missing main(), missing stdio.h, etc.

What happens if you enter 10 and then dd in Command mode in vim?

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

Predict the Output: int a = 10;if (a = 0)    printf(“Hello”);else    printf(“World”); Explain what is printed and why? Consider the code is fully formed, i.e., no excuses like missing main(), missing stdio.h, etc.
