How to store 2 digit integer value and float values in char array in C -

following c code print values of char getting unexpected results. code

#include<stdio.h>  main() {    char sendbuffer[1000];   float count;   int i;   for(count=1.5;count<=2.5;)   {    for(i=0;i<=15;)    {      sendbuffer[0]=count+48;      sendbuffer[1]='a';      sendbuffer[2]='b';      sendbuffer[3]='c';      sendbuffer[4]=i+48;      sendbuffer[5]='\0';      printf("%s\n",sendbuffer);      i=i+5;     }    count=count+0.5;   } } 

the results getting are:

1abc0 1abc5 1abc: 1abc? 2abc0 2abc5 2abc: 2abc? 2abc0 2abc5 2abc: 2abc? 

whereas, expecting

1.5abc0 1.5abc5 1.5abc10 1.5abc15  

and on. can tell me how store integer , float values in char array in c?

this can work:

snprintf(sendbuf, sizeof(sendbuf), "%.1fabc%d", count, i);
