Answer 1

Hello learner,

Thanks for the question.

Question 31:

8/5*25-> when 8/5 in C, as both 8 & 5 are integer it will give remainder output that 1 and when 1*2.5 it will given output as 2.5.

So the answer is 2.5.

Question 32:

As for loop has 3 parts i.e. intialization, condition & increment. In the intialization we can’t use ==.

So correct answer is option 3.

Question 33:

Yes, function protype(return type, argument sequence and argumnet type ) while function declaration, function defination and function calling must match otherwise the compiler will given error.

So answer is True.

Question 34:

Output of the below code will be 37, because in C when 75.5/2.0 it will give result as 37.75 but as the varaiable new_ temperature is integer type, So the values after decimal is ignored and hence the answer is 37.

double temperature = 75.5;

int new_temperature;

new_temperature = temperature/2.0;

So the answer will be 37.

Question 35:

If the functions return type is void that means it shouldn’t return anything. Soit can’t return an expression or any variable.

So the answer will be true.

Question 36:

In C, the datatype of actual argument and corresponding formal argument must be the same, otherwise the compiler will throw error.

So the statement given is false

Question 37:

The for loop in the given statement will run for 5 time.
Initially the count value will be 1, after the first loop it will be increment by 3 ,5 , 7 , 9, 11.

When the count value is 11 then the for loop condition will fail and program

execution will come out.

So the answer is 5.

Question 38:

Yes, we can use while loop for reading the content of the file. Please find the below sample code:

#include <stdio.h>

int main() {

char ch

FILE *f;

f= fopen ('sample.txt', 'r');

while( (ch = getc(f)) != EOF) {

printf('%ch', ch);

}

fclose(fp);

return 0;

}

So the statement given is false.

Question 39:

We can’t have “;” at the end of for loop because adding semicolon at the end will not execute any statement after this until the loop exit.

So the answer will be “;”.

Question 40:

We can use while loop to read the content of the file, As I have provide a sample code of reading the file in Question 38.

So answer is while() loop.
