Discussion Forum : Floating Point Issues - Find Output of Program (Q.No. 7)
7.
What will be the output of the program?
#include<stdio.h>
int main()
{
float a=0.7;
if(a < 0.7f)
printf("C\n");
else
printf("C++\n");
return 0;
}
Answer: Option
Explanation:
if(a < 0.7f) here a is a float variable and 0.7f is a float constant. The float variable a is not less than 0.7f float constant. But both are equal. Hence the if condition is failed and it goes to else it prints 'C++'
Example:
#include<stdio.h>
int main()
{
float a=0.7;
printf("%.10f %.10f\n",0.7f, a);
return 0;
}
Output:
0.6999999881 0.6999999881

%0.10f It specifies the number of digits to be printed after the decimal (.) whereas %f is the regular format specifier
