The convert() function is called in Line 11. This program takes an integer, character and floating point number as input from user using scanf function and stores them in 'inputInteger', 'inputCharacter' and 'inputFloat' variables respectively. The % operator is only defined for integer type operands; you'll need to use the fmod* library functions for floating-point types: consider : int 32 bit and long long int of 64 bits.
