[amp_mcq option1=”the insertion operator” option2=”seekg()” option3=”writeQ” option4=”put()” correct=”option1″]<\/p>\n

The correct answer is A. the insertion operator.<\/p>\n

The insertion operator is used to write data to an output stream. It is denoted by the insertion operator symbol (<<). The insertion operator can be used to write data of any type, including variables of type float.<\/p>\n

The following code snippet shows how to use the insertion operator to write a variable of type float to an output stream:<\/p>\n

“`<\/p>\n

include <\/h1>\n

int main() {
\n float f = 3.14;
\n std::cout << f << std::endl;
\n return 0;
\n}
\n“`<\/p>\n

The output of the above code snippet is:<\/p>\n

3.14<\/code><\/p>\n

The seekg() function is used to reposition the read\/write pointer of an output stream. The writeQ function is not a valid function in C++. The put() function is used to write a single character to an output stream.<\/p>\n

I hope this helps!<\/p>\n","protected":false},"excerpt":{"rendered":"
