Output: ‘91293’

Output: 9.120000E+02

Explanation: The %d format specifier converts the arguments into those given in option ‘1.000000e-01 2.000000e-01 3.000000e-01’. But we have not given a, after .2. So, .3 is not even considered an argument and .2.3 together results in an error.

Explanation: The input to the disp command is a cellular array. Cellular arrays are displayed within []. Output: [12]

Explanation: The size command returns the nature of input given to the command. Here we have given an empty string as an input but the size of the string will return the number of rows and columns present in the input string which is 0 and 0. The ‘’ indicates a 2-D character array which has 0 rows and 0 columns; 0 is treated as a value while returning the size of the input.

Explanation: %4.2f implies that the input argument, 2.9121, will be approximated to 4 places places before the decimal point and 2 places after it.

Explanation: Both would give an error due to absence of any input arguments in the commands. But sprintf() will give an error first as MATLAB returns the first error it finds.

Explanation: No output arguments can be initialized by the disp command. It would have displayed 234 only if the command was disp(234) but here there will be error because we are assigning the output of the disp command to a variable. This is possible by the sprintf command.

Explanation: We can create a character array using the sprintf command and we can use format specifiers in the sprintf command. So, the final character array can be printed by giving that variable as an input to the disp command.

Explanation: The string argument, given as an input to the disp() command, can be given within “” and hence, the output is 12 only. There rest of the options are incorrect.

Explanation: Since we haven’t mentioned a precision while representing .123, the output will be upto 6 places of decimal. Thus, the output is .123000 and there is no error.
