Suppose we have two integer numbers a, b and two floating point numbers c, d. We shall have to find the sum of a and b as well as c and d. We also have to find the sum of a and c as well. So depending on the printf function style, output may differ.
So, if the input is like a = 5, b = 58 c = 6.32, d = 8.64, then the output will be a + b = 63 c + d = 14.960001 a + c = 11.320000
To solve this, we will follow these steps −
To print a + b, they both are integers, so printf("%d") will work
To print c + d, they both are floats, so printf("%f") will work
To print a + c, as one of them is integer and another one is float so we shall have to use printf("%f") to get correct result.
Example
Let us see the following implementation to get better understanding −
#include <stdio.h>
int main(){
int a = 5, b = 58;
float c = 6.32, d = 8.64;
printf("a + b = %d\n", a + b);
printf("c + d = %f\n", c + d);
printf("a + c = %f\n", a + c);
}
Input
a = 5, b = 58; c = 6.32, d = 8.64;
Output
a + b = 63 c + d = 14.960001 a + c = 11.320000
