I need to form a string, inside each iteration of the loop, which contains the loop index i
:
for(i=0;i<100;i++) {
// Shown in java-like code which I need working in c!
String prefix = "pre_";
String suffix = "_suff";
// This is the string I need formed:
// e.g. "pre_3_suff"
String result = prefix + i + suffix;
}
I tried using various combinations of strcat
and itoa
with no luck.
Use sprintf
(or snprintf
if like me you can't count) with format string "pre_%d_suff"
.
For what it's worth, with itoa/strcat you could do:
char dst[12] = "pre_";
itoa(i, dst+4, 10);
strcat(dst, "_suff");
