#include<stdio.h>

int main()
{

    printf("%2.1f\n", a);
    return 0;
}

A 3.00

B 3.15

C 3.2

D 3

ANS:C - 3.2

float a=3.15529; The variable a is declared as an float data type and initialized to value 3.15529; printf("%2.1f\n", a); The precision specifier tells .1f tells the printf function to place only one number after the .(dot). Hence the output is 3.2
